Hello!
I've just upgraded dovecot from 2.0.18 to 2.1.8 and configured impac. I
notice dovecot/imap throws segfault from time to time. I'm not sure i
know what steps are needed to reproduce problem.
I'm using gentoo, hardened-kernel-3.4.2. Namespaces (and settings for
imapc) are keept in database so i'm not sure doveconf would be useful.
If would be needed please let me know.
Thanks
Marcin
