I have 4 new backtraces logged into /tmp/dovecot.log.
I have added line "mail_drop_priv_before_exec: yes" to dovecot11.conf,
and verified that userdb, both static and from passwd file, returns user
homes, and these homes are owned by user vmail specified in
/etc/postfix/master.cf to run dovecot11 service. And can't find any core
files written anywhere. What I'm missing? How to get coredumps of
delivery agent?

I have read once more wiki pages about using dovecot delivery, and
discovered that postfix configuration is missing a line
---
dovecot11_destination_recipient_limit = 1
---
May be, it's related to the problem? It looks like last cases of the
problem occur at the time of bursts of mails arriving to postfix. I have
added this line and will continue testing.
