My default postfix was configured to handle messages upto 20MB. We have tried to send a local email bigger than this and it was found stuck in the queue. The postfix setting message_size_limit was raised and tried to re run the queue meanwhile I could see two local emails in the system are not getting delivered.
(lost connection with host.xxxx.com[private/dovecot-lmtp] while
sending end of data -- message may be sent more than once)
This mail is not even sent which is 100% sure. As this is an email communication between the local domain. I could check each recipient and none of the users have received it. I wanted to force it to send it again and deliver the mail. Is that possible?
I have gone through lots of forum topics and most of the cases users have mentioned it as an "MTU problem". I am unable to try this as the instance where we face the issue is running with aws.
