How to automatically mark stale threads for deletion.
I’ve moved back to mutt after being exiled to kmail, evolution, thunderbird and even gnus for the longest time. The only reason I left mutt in the first place was that I’d moved from POP to IMAP and mutt’s IMAP support was less than stellar at the time. That seems to have improved a lot since then and I’ve found out about some IMAP <-> maildir syncing programs. After some testing offlineimap came out as my winner. I haven’t bother to configure mutt to use IMAP. Using local maildirs instead I circumvent the entire IMAP-caching issue. Plus I have access to my mail when offline.
