notifications strip slashes from email addresses

[bpkroth@…]

We setup aliases in sendmail like group/mytestgroup@domain.com populated with the members of mytestgroup for easy/simplistic list aliases. The left hand side of these appears to be getting stripped when sending email through trac's smtp_notification features so that the logs show it only sending messages to mytestgroup@domain.com which typically isn't a valid alias.

I'm running trac from Debian Squeeze - 0.11.7.

Let me know if you need anything else.

Thanks, Brian

Right, we're a bit too restrictive here. Wikipedia says that the local-part of the e-mail address may use any of the following ASCII characters:

• Uppercase and lowercase English letters (a–z, A–Z)
• Digits 0 to 9
• Characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~
• Character . (dot, period, full stop) provided that it is not the first or last character, and provided also that it does not appear two or more times consecutively

​RFC5322, section 3.4.1 seems to be the authoritative source. We won't add the = back (see #9898), but the others are candidates.
