Is this proxying LMTP traffic?

Based on this I was thinking it wouldn't be. But this apparently happens only with sending SMTP/LMTP traffic with SSL. So do you think it's SSL-related with you also? https://www.dovecot.org/pipermail/dovecot/2018-November/113532.html https://www.dovecot.org/pipermail/dovecot/2018-November/113532.html

Yes, it is. The main server is, currently, doing standard
IMAP/POP3/LMTP for some clients and also proxying IMAP/POP3/LMTP for
other clients (proxying to other servers). But this one error is
related to one message which is stucked in postfix queue and cannot be
delivered - the error appears everytime i do 'postfix flush' (error in
postfix queue is 'lost connection with
<censored-domain-of-main-server>[private/dovecot-lmtp] while sending
end of data -- message may be sent more than once').
There are no errors logged on proxy backend side.

We are, currently, not using SSL while proxying traffic.

Just to clarify this - that one message is to be proxied to other server.

Fix is included in 2.3.5.
