Could it be that dovecot uses setuid to change permissions?
Application would need 'prctl(PR_SET_DUMPABLE, 1);'
according to http://kbase.redhat.com/faq/docs/DOC-4897,
since this distro doesn't have
/proc/sys/kernel/core_setuid_ok

I tried using a pristine 1.1.11 source build with a
core_pattern directory that was owned by root, or by
dovecot, or by the user, but I still didn't see a core
there.
