    33
     
    88Disabled by default, notification can be activated and configured in [wiki:TracIni trac.ini].
    99
    10 == Receiving Notification Mails ==
    11 When reporting a new ticket or adding a comment, enter a valid email address or your username in the ''reporter'', ''assigned to/owner'' or ''cc'' field. Trac will automatically send you an email when changes are made to the ticket (depending on how notification is configured).
    12 
    13 This is useful to keep up-to-date on an issue or enhancement request that interests you.
    14 
    15 === How to use your username to receive notification mails ===
    16 
    17 To receive notification mails, you can either enter a full email address or your username. To get notified with a simple username or login, you need to specify a valid email address in the ''Preferences'' page.
    18 
    19 Alternatively, a default domain name ('''`smtp_default_domain`''') can be set in the TracIni file (see [#ConfigurationOptions Configuration Options] below). In this case, the default domain will be appended to the username, which can be useful for an "Intranet" kind of installation.
    20 
    21 == Configuring SMTP Notification ==
     10== Receiving Notification Mails
     11
     12When reporting a new ticket or adding a comment, enter a valid email address or your Trac username in the ''reporter'', ''assigned to/owner'' or ''cc'' field. Trac will automatically send you an email when changes are made to the ticket, depending on how notification is configured.
     13
     14=== How to use your username to receive notification mails
     15
     16To receive notification mails, you can either enter a full email address or your Trac username. To get notified with a simple username or login, you need to specify a valid email address in the ''Preferences'' page.
     17
     18Alternatively, a default domain name ('''`smtp_default_domain`''') can be set in the TracIni file, see [#ConfigurationOptions Configuration Options] below. In this case, the default domain will be appended to the username, which can be useful for an "Intranet" kind of installation.
     19
     20When using apache and mod_kerb for authentication against Kerberos / Active Directory, usernames take the form ('''`[email protected]`'''). To avoid this being interpreted as an email address, add the Kerberos domain to  ('''`ignore_domains`''').
     21
     22=== Ticket attachment notifications
     23
     24Since 1.0.3 Trac will send notifications when a ticket attachment is added or deleted. Usually attachment notifications will be enabled in an environment by default. To disable the attachment notifications for an environment the `TicketAttachmentNotifier` component must be disabled:
     25{{{#!ini
     26[components]
     27trac.ticket.notification.TicketAttachmentNotifier = disabled
     28}}}
     29
     30== Configuring SMTP Notification
    2231
    2332'''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].
    2433
    25 === Configuration Options ===
    26 These are the available options for the `[notification]` section in trac.ini.
    27 
    28  * '''`smtp_enabled`''': Enable email notification.
    29  * '''`smtp_from`''': Email address to use for ''Sender''-headers in notification emails.
    30  * '''`smtp_from_name`''': Sender name to use for ''Sender''-headers in notification emails.
    31  * '''`smtp_replyto`''': Email address to use for ''Reply-To''-headers in notification emails.
    32  * '''`smtp_default_domain`''': (''since 0.10'') Append the specified domain to addresses that do not contain one. Fully qualified addresses are not modified. The default domain is appended to all username/login for which an email address cannot be found from the user settings.
    33  * '''`smtp_always_cc`''': List of email addresses to always send notifications to. ''Typically used to post ticket changes to a dedicated mailing list.''
    34  * '''`smtp_always_bcc`''': (''since 0.10'') List of email addresses to always send notifications to, but keeps addresses not visible from other recipients of the notification email
    35  * '''`smtp_subject_prefix`''': (''since 0.10.1'') Text that is inserted before the subject of the email. Set to "!__default!__" by default.
    36  * '''`always_notify_reporter`''':  Always send notifications to any address in the reporter field (default: false).
    37  * '''`always_notify_owner`''': (''since 0.9'') Always send notifications to the address in the owner field (default: false).
    38  * '''`always_notify_updater`''': (''since 0.10'') Always send a notification to the updater of a ticket (default: true).
    39  * '''`use_public_cc`''': (''since 0.10'') Addresses in To: (owner, reporter) and Cc: lists are visible by all recipients (default is ''Bcc:'' - hidden copy).
    40  * '''`use_short_addr`''': (''since 0.10'') Enable delivery of notifications to addresses that do not contain a domain (i.e. do not end with ''@<domain.com>'').This option is useful for intranets, where the SMTP server can handle local addresses and map the username/login to a local mailbox. See also `smtp_default_domain`. Do not use this option with a public SMTP server.
    41  * '''`mime_encoding`''': (''since 0.10'') This option allows selecting the MIME encoding scheme. Supported values:
    42    * `none`: default value, uses 7bit encoding if the text is plain ASCII, or 8bit otherwise.
    43    * `base64`: works with any kind of content. May cause some issues with touchy anti-spam/anti-virus engines.
    44    * `qp` or `quoted-printable`: best for european languages (more compact than base64) if 8bit encoding cannot be used.
    45  * '''`ticket_subject_template`''': (''since 0.11'') A [http://genshi.edgewall.org/wiki/Documentation/text-templates.html Genshi text template] snippet used to get the notification subject.
    46  * '''`email_sender`''': (''since 0.12'') Name of the component implementing `IEmailSender`. This component is used by the notification system to send emails. Trac currently provides the following components:
    47    * `SmtpEmailSender`: connects to an SMTP server (default).
    48    * `SendmailEmailSender`: runs a `sendmail`-compatible executable.
    49 
    50 Either '''`smtp_from`''' or '''`smtp_replyto`''' (or both) ''must'' be set, otherwise Trac refuses to send notification mails.
    51 
    52 The following options are specific to email delivery through SMTP.
    53  * '''`smtp_server`''': SMTP server used for notification messages.
    54  * '''`smtp_port`''': (''since 0.9'') Port used to contact the SMTP server.
    55  * '''`smtp_user`''': (''since 0.9'') User name for authentication SMTP account.
    56  * '''`smtp_password`''': (''since 0.9'') Password for authentication SMTP account.
    57  * '''`use_tls`''': (''since 0.10'') Toggle to send notifications via a SMTP server using [http://en.wikipedia.org/wiki/Transport_Layer_Security TLS], such as GMail.
    58 
    59 The following option is specific to email delivery through a `sendmail`-compatible executable.
    60  * '''`sendmail_path`''': (''since 0.12'') Path to the sendmail executable. The sendmail program must accept the `-i` and `-f` options.

     63=== Customizing the e-mail subject
     64
    8465The e-mail subject can be customized with the `ticket_subject_template` option, which contains a [http://genshi.edgewall.org/wiki/Documentation/text-templates.html Genshi text template] snippet. The default value is:
    8566{{{
    8667$prefix #$ticket.id: $summary
    8768}}}
     69
    8870The following variables are available in the template:
    8971
     
    9173 * `prefix`: The prefix defined in `smtp_subject_prefix`.
    9274 * `summary`: The ticket summary, with the old value if the summary was edited.
    93  * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, e.g. `$ticket.milestone`.
    94 
    95 === Customizing the e-mail content ===
    96 
    97 The notification e-mail content is generated based on `ticket_notify_email.txt` in `trac/ticket/templates`.  You can add your own version of this template by adding a `ticket_notify_email.txt` to the templates directory of your environment. The default looks like this:
     75 * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, eg `$ticket.milestone`.

     143== Customizing e-mail content for MS Outlook
     144
     145MS Outlook normally presents plain text e-mails with a variable-width font, and as a result the ticket properties table will most certainly look like a mess in MS Outlook. This can be fixed with some customization of the [#Customizingthee-mailcontent e-mail template].
     146
     147Replace the following second row in the template:
     148{{{
     149$ticket_props
     150}}}
     151
     152with this (requires Python 2.6 or later):

     155{% with
     156   pv = [(a[0].strip(), a[1].strip()) for a in [b.split(':') for b in
     157         [c.strip() for c in
     158          ticket_props.replace('|', '\n').splitlines()[1:-1]] if ':' in b]];
     159   sel = ['Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',
     160          'Component', 'Severity', 'Resolution', 'Keywords'] %}\

     162{% end %}\
     163--------------------------------------------------------------------------
     164}}}
     165
     166The table of ticket properties is replaced with a list of a selection of the properties. A tab character separates the name and value in such a way that most people should find this more pleasing than the default table when using MS Outlook.

     201
     202**Important**: Only those ticket fields that are listed in `sel` are part of the HTML mail. If you have defined custom ticket fields which are to be part of the mail, then they have to be added to `sel`. Example:
     203{{{
     204   sel = ['Reporter', ..., 'Keywords', 'Custom1', 'Custom2']
     205}}}
     206
     207However, the solution is still a workaround to an automatically HTML-formatted e-mail.
     208
     209== Using GMail as the SMTP relay host
     210
     211Use the following configuration snippet:
     212{{{#!ini
    163213[notification]
    164214smtp_enabled = true
     
    171221}}}
    172222
    173 where ''user'' and ''password'' match an existing GMail account, ''i.e.'' the ones you use to log in on [http://gmail.com]
     223where ''user'' and ''password'' match an existing GMail account, ie the ones you use to log in on [http://gmail.com].
    174224
    175225Alternatively, you can use `smtp_port = 25`.[[br]]
    176 You should not use `smtp_port = 465`. It will not work and your ticket submission may deadlock. Port 465 is reserved for the SMTPS protocol, which is not supported by Trac. See [comment:ticket:7107:2 #7107] for details.

    177227 
    178 == Filtering notifications for one's own changes ==
    179 In Gmail, use the filter:
    180 
    181 {{{
    182 from:(<smtp_from>) (("Reporter: <username>" -Changes) OR "Changes (by <username>)")
    183 }}}
    184 
    185 For Trac .10, use the filter:
     228== Filtering notifications for one's own changes and comments
     229
     230To delete these notifications in Gmail, use the following filter:
    186231{{{
    187232from:(<smtp_from>) (("Reporter: <username>" -Changes -Comment) OR "Changes (by <username>)" OR "Comment (by <username>)")
    188233}}}
    189234
    190 to delete these notifications.
    191 
    192 In Thunderbird, there is no such solution if you use IMAP
    193 (see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body).
    194 
    195 The best you can do is to set "always_notify_updater" in conf/trac.ini to false.
    196 You will however still get an email if you comment a ticket that you own or have reported.
     235In Thunderbird, there is no such solution if you use IMAP, see http://kb.mozillazine.org/Filters_(Thunderbird)#Filtering_the_message_body.

     240== Troubleshooting
    202241
    203242If you cannot get the notification working, first make sure the log is activated and have a look at the log to find if an error message has been logged. See TracLogging for help about the log feature.
    204243
    205 Notification errors are not reported through the web interface, so the user who submit a change or a new ticket never gets notified about a notification failure. The Trac administrator needs to look at the log to find the error trace.
    206 
    207 === ''Permission denied'' error ===

    209248Typical error message:

    216255
    217 This error usually comes from a security settings on the server: many Linux distributions do not let the web server (Apache, ...) to post email message to the local SMTP server.
     256This error usually comes from a security settings on the server: many Linux distributions do not allow the web server (Apache, ...) to post email messages to the local SMTP server.
    218257
    219258Many users get confused when their manual attempts to contact the SMTP server succeed:
    220 {{{
     259{{{#!sh
    221260telnet localhost 25
    222261}}}
    223 The trouble is that a regular user may connect to the SMTP server, but the web server cannot:
    224 {{{
     262
     263This is because a regular user may connect to the SMTP server, but the web server cannot:
     264{{{#!sh
    225265sudo -u www-data telnet localhost 25
    226266}}}
    227267
    228 In such a case, you need to configure your server so that the web server is authorized to post to the SMTP server. The actual settings depend on your Linux distribution and current security policy. You may find help browsing the Trac [trac:MailingList MailingList] archive.
    229

    232271
    233272For SELinux in Fedora 10:
    234 {{{
    235 $ setsebool -P httpd_can_sendmail 1
    236 }}}
    237 === ''Suspected spam'' error ===

     275}}}
     276
     277=== ''Suspected spam'' error
    238278
    239279Some SMTP servers may reject the notification email sent by Trac.
    240280
    241 The default Trac configuration uses Base64 encoding to send emails to the recipients. The whole body of the email is encoded, which sometimes trigger ''false positive'' SPAM detection on sensitive email servers. In such an event, it is recommended to change the default encoding to "quoted-printable" using the `mime_encoding` option.
    242 
    243 Quoted printable encoding works better with languages that use one of the Latin charsets. For Asian charsets, it is recommended to stick with the Base64 encoding.
    244 
    245 === ''501, 5.5.4 Invalid Address'' error ===
    246 
    247 On IIS 6.0 you could get a
    248 {{{

     281The default Trac configuration uses Base64 encoding to send emails to the recipients. The whole body of the email is encoded, which sometimes trigger ''false positive'' spam detection on sensitive email servers.
