[SOLVED] Problems with E-Mail, can't send from Gmail but from Drupal

[Maurizio]

Hello there,

i've a problem with my SMTP settings. And I know that there are already many posts about that.
But not like my case.

The strange thing is that my drupal site, which is located on the server can send mails. But when i try to send from Gmail it does not work.

SMTP-Settings on Gmail
Server: IP-Adress/ or Domainname
Port: 25
User: E-Mail adress
and password

I've also tryed several combinations, it still does nothing.

Gmail is showing that it has send the Mail but after a few hours it arrives an email that says:

Action: failed
Status: 4.3.0
Diagnostic-Code: X-Postfix; local data error while talking to
smtp.mailchannels.net[54.214.
243.124]

Ask when you need mor info ;-)

I've partly solved the problem,with the connection to the server is all ok!
The problem is in my Home Network, there I've to find the problem.

Problem solved!

It was the Firewall of one of my routers which blocked the smtp.
