Is dovecot still considered unreliable when combined with NFS?
Is this true for mbox only, or Maildir as well?
If dovecot Is still considered unreliable with NFS, how about having a dovecot mode that would chain into procmail for delivery, so that dovecot doesn't (necessarily) have to reinvent that wheel?
I'm not sure what Procmail has to do with NFS unreliability. You can use Procmail to store the incoming messages, but the problems come when mailbox is actually being accessed with IMAP/POP3.
The problem isn't in either mbox or maildir, it's Dovecot's index files. It's of course possible to store indexes to local disk, but if you're using multiple servers you'll get worse performance whenever latest indexes can't be used.
Recent 1.0-tests should be somewhat usable with NFS too. I think someone in this list already is using it.
Yep we are, NFS server with 2x dovecot servers, mailboxes are Maildir and
indexes are stored on local HDDs. Using Mysql master-slaves for user/pass.
Very reliable system, only real problem we had was when the NFS HDD failed.
We now have a redundancy for that too :)
Timo has done some great work to get this kinda thing working.
