I apologise for my luck of understandig of the question, but I need to solve this problem.
A customer is trying to send mail via submission port 587 using a .net application after a sever migration,
the remote ip of the sender is not in
"mynetworks" I need to add it?
I made some test from my IP:
Code: Select all
telnet mail.domain.com 587
Trying 222.222.222.222...
Connected to mail.domain.com.
Escape character is '^]'.
