Hello,
I having some, where 3 out of 4 received the email but 4th one has't received the emai. when i checked the UTM logs even the SMTP proxy live logs I can see the 4th user error saying" lost while reading message data" and then Syscall broken pipe SSL write error 5
It is keep happening and 4 user is not getting email from same client & it is only happening with one client. Current send domain is skipping the Anti-spam check.
I have searched alot about this but no luck.
any help would be much appreciated
Below are the logs
