Only have 650 imap clients this weekend, have to give it a try during
a weekday.

Quoting Timo Sirainen <t...@iki.fi>:
v2.1's imap/pop3 processes are linked with OpenSSL by default,
because of imapc/pop3c storages. I wonder if you notice any actual
(system-global) memory usage reduction when compiling without those
and you have thousands of imap processes?
./configure --with-storages=mdbox sdbox maildir mbox cydir
I guess I could try it myself also but maybe someone else wanting to
reduce memory usage is quicker? :)
Related to that, you can look at where imap processes' memory goes
with: http://dovecot.org/tools/linux-maps-parse-imap.pl
I don't know how much memory those (writable!) file-backed memory
areas actually use per-process. Maybe nothing, maybe something..
