The freebsd-security list is for security issue with the FreeBSD
operating system.
Your question involves a port question. freebsd-questions, cyrus
mailing list, or freebsd-ports is where you should have posted.

You'll need to use gdb on the cyrus-imapd .core file to find out where
it is failing.
You'll also need a version of the cyrus-imapd compiled with debugging
symbols to get something usefull out of gdb.

i.e.

gdb /usr/ports/mail/cyrus-imapd22/work/cyrus-imapd-2.2*/<location of
file>/<name of cyrus-imapd> -c /<location of core file>/<name of
cyrus-imapd>.core

(check the man page, I'm not sure -c is correct for the core file)

then use bt (backtrace) in gdb and it will show you the src file &
function where the failure is occuring. You may also want to look at
the values of some of the variables (i.e. p varname, p *varname, p
&varname)
