Fatal: master: service(imap): child 20258 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes })
All,
Just move our mail servers over to a new mail server running postfix
2.11.1 and dovecot 2.2.13 and getting the subject line errors in my
/var/adm/files. People are complaining of loosing their connections to
the mail server.
I've been able to google this error but haven't found fix for this yet.
NOt sure where to put the drop-priv option in the config files either.
Any suggestions?
Var adm message:
