    1616=== How to use your username to receive notification mails
    1717
    18 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].

    2020Alternatively, 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.

    34 '''Important:''' The [[TracIni#trac-base_url-option|[trac] base_url]] option must be configured for links in the notification message to be correctly generated.

    6262=== Subscriber Configuration
    63 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:
    6464
    6565[[TracIni(section=notification-subscriber)]]
    6666
    67 Each user can override these defaults in their ''Notifications'' preferences.
     67Each user can override these defaults in his ''Notifications'' preferences.
    6868
    6969For 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.
    7070
    71 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.
    72 
    73 The following attributes of default subscriptions can be configured:
    74 * `.distributor` (Default: `email`)
    75   * Other values require plugins. For example `on-site` requires th:OnSiteNotificationsPlugin.
    76 * `.priority` (Default: `100`)
    77   * Smaller values override larger values.
    78   * If you use `0`, then users will not be able to override this rule.
    79 * `.adverb` (Default: `always`)
    80   * `never` can be used to silence other subscription rules with higher values.
    81 * `.format` (Default: `text/plain`)
    82   * Other values require plugins. For example `text/html` requires th:TracHtmlNotificationPlugin.

    102 
    103 === Customizing the email subject
    104 The email subject can be customized with the `ticket_subject_template` option, which contains a [https://genshi.edgewall.org/wiki/Documentation/text-templates.html Genshi text template] snippet. The default value is:
     71=== Customizing the e-mail subject
     72The e-mail subject can be customized with the `ticket_subject_template` option, which contains a [http://genshi.edgewall.org/wiki/Documentation/text-templates.html text template] snippet. The default value is:
    10573{{{#!genshi
    10674${prefix} #${ticket.id}: ${summary}
    … …  
    10876The following variables are available in the template:
    10977
    110  * `changes`: The ticket changes (prepared by [trac:source:/branches/1.4-stable/trac/ticket/model.py Ticket.get_change]).
     78 * `changes`: The ticket changes (prepared by [trac:source:/branches/1.4-stable/trac/ticket/model.py Ticket.get_change]). 
    11179 * `env`: The project environment (see [trac:source:/branches/1.4-stable/trac/env.py env.py]).
    11280 * `prefix`: The prefix defined in `smtp_subject_prefix`.
    11381 * `summary`: The ticket summary, with the old value if the summary was edited.
    114  * `ticket`: The ticket model object (see [trac:source:/branches/1.4-stable/trac/ticket/model.py model.py]). Individual ticket fields can be addressed by appending the field name separated by a dot, eg `${ticket.milestone}`.
    115 
    116 === Customizing the email content #CustomizingContent
    117 
    118 The notification email 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 is:
    119 
    120 {{{#!jinja

    122 ${ticket_props}

     84=== Customizing the e-mail content

     86The 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:

     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.

    199234== Troubleshooting
    200235
    201 If notifications are not working, inspect the [TracLogging log] for error messages.
    202 
    203 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.
