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.>> dovecot/lmtp [local DATA](_start+0x2a) [0x565287c310ca] > > Based on this I was thinking it wouldn't be.
