Re: [Dovecot] Dovecot performance under high load (vs. Courier)

Quoting Ed W lists@wildgooses.com:

I think the conclusion is that imapproxy is not necessary. There
are some advantages (eg with high network latency between web and
imap server, and reducing apparent login count), and some
disadvantages (extra complexity, slowdown)

Not entirely true. See this thread:

http://markmail.org/thread/z7ctwle2go6zafas

Thread in short: imapproxy provides benefits for more MUAs that take
advantage of the XIMAPPROXY feature (only IMP, AFAIK), and Timo is/was
considering adding a similar state saving feature to Dovecot 2.2.
