Connection time out in email server test

Postby rjorodrigues » Tue May 12, 2020 2:55 pm


I am using email server testing sites as a practice to check for possible problems.

I am having the following feedback from all of them.

Release 8.8.15.GA.3829.UBUNTU16.64 UBUNTU16_64 FOSS edition, Patch 8.8.15_P9.

May 12 11:31:29 postfix/postscreen[1024]: DISCONNECT []:19337
May 12 11:32:09 postfix/postscreen[1024]: CONNECT from []:59679 to []:25
May 12 11:32:14 postfix/postscreen[1024]: HANGUP after 4.1 from []:59679 in tests before SMTP handshake

Used Sites:

What do I have to do to allow these tests?

Thanks a lot!
