Hi,

I,m experiencing socket 10053 errors only on a specific email address. The rest of the mail works fine. I did adjust the MTU size to 1472 and did some test to see if the ping then gets through (I wasn`t having troubles with other email addresses with MTU 1500).
But still this mail from my server to another server keeps having socket errors. I,m beginning to think that it,s not my server who`s creating problems, however how do I prove to my customer that this is the case.

Message of my server : ( Mail is only 19kb big)
Socket error 10053 Connection abort
Socket read error
SMTP session terminated (Bytes in/out: 4536/4266)

Mdaemon 21.5.2 on Windows server 2022 ( not supported, i know)
