    8 Disabled by default, notification can be activated and configured in [TracIni trac.ini].
     6Email notification is useful to keep users up-to-date on tickets/issues of interest, and also provides a convenient way to post all ticket changes to a dedicated mailing list. For example, this is how the [http://lists.edgewall.com/archive/trac-tickets/ Trac-tickets] mailing list is set up.

     8Disabled by default, notification can be activated and configured in [wiki:TracIni trac.ini].

    1010== Receiving Notification Mails
    11 When 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.
     11When 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 may send you an email when changes are made to the ticket, depending on how your notification preferences are configured.
     12
     13Permission groups can also be entered in the CC field,
     14to notify all members of the group.
    1215
    1316=== How to use your username to receive notification mails
    1417
    15 To 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 your [/prefs preferences].
     18To 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.
    1619
    1720Alternatively, 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.

    2932== Configuring SMTP Notification

    31 '''Important:''' The [[TracIni#trac-base_url-option|[trac] base_url]] option must be configured for links in the notification message to be correctly generated.
     34'''Important:''' For TracNotification to work correctly, the `[trac] base_url` option must be set in [wiki:TracIni trac.ini].

    5861
    5962=== Subscriber Configuration
    60 The default subscriptions are configured in the [TracIni#notification-subscriber-section "[notification-subscriber]"] section.
     63The default subscriptions are configured in the `[notification-subscriber]` section in trac.ini:
    6164
    6265[[TracIni(section=notification-subscriber)]]
    6366
    64 Each user can override these defaults in their ''Notifications'' preferences.
     67Each user can override these defaults in his ''Notifications'' preferences.
    6568
    6669For example to unsubscribe from notifications for one's own changes and comments, the rule "Never notify: I update a ticket" should be added above other subscription rules.
    6770
    68 The subscription rule name on the left side of the `=` can be anything, it has no meaning outside this configuration file. The subscriber name on the right side of the `=` must be one of the subscribers listed in the above table.
    69 
    70 The following attributes of default subscriptions can be configured:
    71 * `.distributor` (Default: `email`)
    72   * Other values require plugins. For example `on-site` requires th:OnSiteNotificationsPlugin.
    73 * `.priority` (Default: `100`)
    74   * Smaller values override larger values.
    75   * If you use `0`, then users will not be able to override this rule.
    76 * `.adverb` (Default: `always`)
    77   * `never` can be used to silence other subscription rules with higher values.
    78 * `.format` (Default: `text/plain`)
    79   * Other values require plugins. For example `text/html` requires th:TracHtmlNotificationPlugin.

    10981 * `summary`: The ticket summary, with the old value if the summary was edited.
    110  * `ticket`: The ticket model object (see [trac:source:/trunk/trac/ticket/model.py model.py]). Individual ticket fields can be accessed by appending the field name separated by a dot, eg `${ticket.milestone}`.

     149== Customizing e-mail content for MS Outlook
     150
     151MS 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].
     152
     153Replace the following second row in the template:
     154{{{
     155$ticket_props
     156}}}
     157
     158with this (requires Python 2.6 or later):
     159{{{
     160--------------------------------------------------------------------------
     161{% with
     162   pv = [(a[0].strip(), a[1].strip()) for a in [b.split(':') for b in
     163         [c.strip() for c in
     164          ticket_props.replace('|', '\n').splitlines()[1:-1]] if ':' in b]];
     165   sel = ['Reporter', 'Owner', 'Type', 'Status', 'Priority', 'Milestone',
     166          'Component', 'Severity', 'Resolution', 'Keywords'] %}\
     167${'\n'.join('%s\t%s' % (format(p[0]+':', ' <12'), p[1]) for p in pv if p[0] in sel)}
     168{% end %}\
     169--------------------------------------------------------------------------
     170}}}
     171
     172The 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.

     208**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:
     209{{{
     210   sel = ['Reporter', ..., 'Keywords', 'Custom1', 'Custom2']
     211}}}
     212
     213However, the solution is still a workaround to an automatically HTML-formatted e-mail.

    196235
    197 If notifications are not working, inspect the [TracLogging log] for error messages.
    198 
    199 Notification errors are not always reported through the web interface, so the user who submits a change or creates a ticket may not get notified about a notification failure. The Trac administrator needs to look at the log to find the error message and traceback.
     236If 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.
     237
     238Notification errors are not reported through the web interface, so the user who submits 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.
