Increase mail_process_size setting in dovecot.conf or just set it to 0
to disable the limits. Although only 64k messages shouldn't normally use
up the default 256 MB limit.. How large is the dovecot.index.cache file
for those mailboxes? mmaping that file is usually what takes most of the
memory.

This is probably unrelated, but shouldn't happen either. Do you see them
often? Or does it always happen among these out of memory errors?
