Hi,
We have 2 servers, server A and server B.
Server A has:
Postfix dovecot-2.2.33.2-1.el6.x86_64
Server B has:
dovecot-2.2.33.2-1.el6.x86_64 dovecot-pigeonhole-2.2.33.2-1.el6.x86_64
Server A receives email on postfix, dovecot then takes that email from postfix and proxies it to Server B Dovecot. Dovecot on Server B takes the proxied email and delivers it with lmtp to the user inboxes.
The problem is that the dovecot on server B Doesn't log anything regarding the emails that are being delivered to the mailbox via lmtp.
Dovecot on server A logs everything perfectly regarding the proxy, so my assumption is that there is an issue with Dovecot lmtp logging. We changed the logging from syslog directly to a file and we noticed the same problem, missing log entries.
We also tried turning on verbose logging and it didn't help.
Server B:
Red Hat 6.7 x86_64
rpm -qa | grep dove dovecot-2.2.33.2-1.el6.x86_64 dovecot-pigeonhole-2.2.33.2-1.el6.x86_64
