i change the domain with mydomain


I don't know what to change. Another thing, i receive mail from my domain without problem

the error message can be different because i'm trying a lot of thing still sunday

i send again with gmail and become this:

Code: [Select]

Action: delayed
Status: 4.4.1
Diagnostic-Code: smtp; The recipient server did not accept our requests to connect.

Hiding real domain names and/or real IP’s doesn’t help to resolve your issue, but do it more complex to resolve. Is 35.195.101.223 your real IP? (taken from provided output)

Can you test your sever with telnet from other machine, not from localhost?

telnet 35.195.101.223 25 is failed for me. You are firewalled or Postfix listen only at 127.0.0.1:25 ?

Hi PavelZh,

thanks this was the trick. my firewall rules was not correctly setup and i don't know what's happen, like i said the emails worked great until last sunday.

Anyway i just reopen the incomming port 25 and everything work fine now.
I'm on google cloud engine and google block outgoing port 25.

All ok, Thanks Pavel for your light...

Hi
I also have a strange mail problem. I can send mail just fine, I can receive from Gmail, Yahoo, mail.com, fastmail (basically all webmail clients I have tried), but cannot receive mail from other hosts (custom email addresses). Plese note that I'm using Gmail with Thunderbird and it works.
I'm tailing /var/log/maillog and I receive no error when sending from custom host, it's just like the mail doesn't even hit my mail server. And no error mail returns to sender either. My leafdns also looks ok, scores 100%: http://leafdns.com/index.cgi?testid=F914F3DE
Any ideeas? Thanks!
