I’ve recently been forced to move my mail to a virtual hosting environment. Doing this has been a bit of a pain because of a lot of historical use and abuse of user-extension@domain type email addresses. While migrating away from them and realizing that my hosting provider didn’t provide me with a great strategy for manipulation of procmailrc files, I’ve been forced to look into IMAP client based filtering.
The first thing I noticed is that Thunderbird doesn’t by default allow you to filter on List ID headers. You can add this in through the gui, but it effectively amounts to this tweak in your prefs.js file:
user_pref("mailnews.customHeaders", "List-Id");
I also use the following tweak which attributes quotes in email replies:
user_pref("mailnews.reply_header_type", 2);
What I’m currently hunting for is a Reply-to-list tweak or extension. This is the only piece I’m missing from a fully functional MUA setup. It’s a pretty big problem for me at the moment. If anyone has any suggestions, I’m all ears.
As far as XPI extensions go, I’m currently using Enigmail for PGP signing my email and World Weather to virtually experience the outdoors without breaking a sweat…
