Trac Notify SMTP Socket Error

[trac at zippy6.net]

The Scenario

We have e-mail notification enabled on our Trac installation, and it is working fine. However, our system adminstrators took down the mail server last night for regularly scheduled maintanence. During this time I attempted to create a new ticket. After hitting the Submit ticket button, the web page never refreshed, and so I hit the Submit ticket a few more times.

Going to the View Tickets tab, I saw that the ticket really was created … three copies were created. The Trac server got confused when it could not open a socket connectin to the mail server.

This behavior could be related to #980

Indeed, as far as I can tell, this is a duplucate of #980. The problem has been fixed in trunk and will be in the upcoming 0.9 release.
