I'm quitting GMail but attempting to avoid the headaches that come with administering my own Internet-facing IMAP server. I have access to a commercial IMAP account, and I'd like to continue to use that account.
Basically the way I'd like it to work is that mail is downloaded to my server and deleted from my mailbox on the commercial IMAP server. Then once on my server it's served up via IMAP and webmail, so that it can be used on mobile + internet devices, and remains in sync across both.
Things it must do:
- Be accessible from all devices
- Relatively fast searching
- Threaded viewing of message replies (preferably with my sent mails interspersed)
Here's how I see it working:
Mail arrives at commercial IMAP server -> On my server, fetchmail downloads via IMAP and delivers to -> MDA/MTA, which updates a search cache for rapid searching and makes it available via IMAP to -> Horde IMP, which caches the e-mails in the inbox for faster previewing
I'm looking for an MDA/MTA pair that can be delivered to by fetchmail, emphasizes security, and supports search cacheing on this scale (so when I search the inbox in IMP it doesn't take forever). My plan is to be GMail-like in that I'll likely not put things in folders but leave everything in the Inbox and search it when I need to find anything.
Any other thoughts on the sanity/insanity of this welcome, but my main concern is the MDA/MTA.
