            | 5 |   |  | 
          
          
            | 6 |   | Email 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. |

            | 25 |   |  * '''smtp_replyto''': Email address to use for ''Reply-To''-headers in notification emails. | 
          
          
            | 26 |   |  * '''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. | 
          
          
            | 27 |   |  * '''smtp_always_cc''': List of email addresses to always send notifications to. ''Typically used to post ticket changes to a dedicated mailing list.'' |

            | 31 |   |  * '''always_notify_owner''': (''since 0.9'') Always send notifications to the address in the owner field (default: false). |

See also `smtp_default_domain`. Do not use this option with a public SMTP server.  | 
          
          
            | 35 |   |  * '''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. | 
          
          
            | 36 |   |  * '''mime_encoding''': (''since 0.10'') E-mail notifications are always sent in 7-bit mode. This option allows to select the MIME encoding scheme. Supported values: | 
          
          
            | 37 |   |    * `base64`: default value, works with any kind of content. May cause some issues with touchy anti-spam/anti-virus engines. | 
          
          
            | 38 |   |    * `qp` or `quoted-printable`: best for european languages (more compact than base64), not recommended for non-ASCII text (less compact than base64) | 
          
          
            | 39 |   |    * `none`: no encoding. Use with plain english only (ASCII). E-mails with non-ASCII chars won't be delivered.  | 
          
          
            | 40 |   |  | 
          
          
            | 41 |   | Either '''smtp_from''' or '''smtp_replyto''' (or both) ''must'' be set, otherwise Trac refuses to send 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 may send you an email when changes are made to the ticket, depending on how your notification preferences are configured. |

            |   | 16 | === How to use your username to receive notification mails | 
          
          
            |   | 17 |  | 
          
          
            |   | 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]. | 
          
          
            |   | 19 |  | 
          
          
            |   | 20 | 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. | 
          
          
            |   | 21 |  | 
          
          
            |   | 22 | When using apache and mod_kerb for authentication against Kerberos / Active Directory, usernames take the form ('''`username@EXAMPLE.LOCAL`'''). To avoid this being interpreted as an email address, add the Kerberos domain to ('''`ignore_domains`'''). |

            |   | 75 |   * Other values require plugins. For example `on-site` requires [https://trac-hacks.org/wiki/OnSiteNotificationsPlugin 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`) |
