That did it. Thank you so much for your help.

I still didn't get a core dump in /var/run/dovecot. Should I be looking
somewhere else? That is the directory that the base_dir variable is set to
in my dovecot.conf file.

I tried this with both the allow_all_users set and without it set. That was
the fix though. By adding allow_all_users to my userdb static args,
everything is running just fine.
