[Dovecot] Wanting to seperate MTA and Imap
Hi
Current my set up is that the MTA and Dovecot (maildir) is on the same machine. Ive been asked to seperate the services from the same machine (too would like to add a secondary MTA - but thats future ideas).
I read the documentation on NFS, but from other sites i have read. Most say this is NOT the best solution.
My question is, how do some of the fellow dovecot users,or other companys, e.g. google etc, pull this off.
If you can assist in helping me fine a solution and too help me understand, I would greatfully appreciate it.
Kind Regards Brent Clark
Why can't you have a lightweight MTA on the dovecot server that only
accepts from your primary MTA? That seems to be the simplest and most
reliable solution.
After all, its not like an mta is going to cost you anything!

I use NFS, as do quite a number of people - it may not be the best solution, but there are few others for realising shared storage at all sensibly. Most of the cluster filesystems I've tested have not performed well, and I'm guessing you don't have access to a quality SAN to make this sensible.
If you read the doco in the Dovecot wiki regarding NFS you should be moving in the right direction. My only suggestion is that creating local caches/indexes (ie - not residing on NFS) on your IMAP servers is a good idea - hint: check out the Dovecot doco on 'mail_location'.

Have you tested Redhat's GFS? If yes, how it behave with Dovecot imap/lda?

One possibility would be a LMTP server. http://pll.sf.net/ has been used successfully at least.
