Hello,

It's a brand new installation of cPanel on CENTOS 6.8 x86_64 virtuozzo and it's giving the following error.

Code:
..................................................................................................................................................................

2016-08-26 08:06:38 SMTP connection from [::1]:42786 (TCP/IP connection count = 1)

IP 123.123.123.123 is my IP /not the real one

iptables have been stopped , rDNS have been setup .


Telnet on port 25 , 587 is answering

Escape character is '^]'.

Any ideas what might have cause that will be appreciated.


Thank You!

Which error are you referring to? Are mails not getting delivered?

Whatever it is outputting is normal behaviour.

After the end of an SMTP "conversation" the connection is deliberately closed by issuing a QUIT command.

Escape character is '^]'.

220-We do not authorize the use of this system to transport unsolicited,
220 and/or bulk e-mail.
The above is also a normal welcome message.

Did the mail in question not get delivered? If so, what was the bounce message like?

I manage to figure it out , my VPS provider is blocking "outgoing" email ports on a "router level" .

p.s. When i was posting the topic i wasn't allowed to edit it , that's why i'm missing the actual error. :


Code:
