I don't think so. This directory contains all my NetBSD mailing lists:

# du -hs /mail/cyrus/data/user/martti/lists/netbsd
21M     /mail/cyrus/data/user/martti/lists/netbsd

# cd /mail/cyrus/data/user/martti/lists/netbsd
# ls -lh imapd.core
-rw-------  1 cyrus  mail   21M Oct 20 11:25 imapd.core
# ls -l | wc -l
       26

> Connect to imap server for a long time?

Usually 5 days (from Monday morning until Friday afternoon).
