http://trac.edgewall.org/wiki/TracNotification官网上提供的方法。个人觉得不是清楚，不过还是有参考价值的。以下写下自己的添加过程，以作记录。
1.the [trac] base_url option must be set in trac.ini.
base_url=http://110.28.136.186:8000/mytrac
2.[components]
acct_mgr.notification.* = enabled
3.这一步也是最关键的，也是弄了我好久，smtp_from_name，smtp_user网上很多都是直接使用postmaster帐号名，使用帐号名就出现
问题'Authentication failure[0]'，将它们改成邮件的格式，并且一定要相同才能使用！
