is Amavisd running?
Make sure Amavisd is running on target server and its listening on port 10025

post the output  - netstat -tulpn | grep 10025

[royer_guerra@hotmail.com]

Code Select Expand

[root@cwp ~]# netstat -tulpn | grep 10025
tcp        0      0 127.0.0.1:10025         0.0.0.0:*               LISTEN      29681/master


Yes Amavis is running, is rarely , because many emails is coming to this email server.
Only appears this error when I sent since other server., example, in the other server I have  two domains, 1 domain can send very well, second domain cant send emails this server.. appears this error.

Did you try to restart amavis?

service amavisd restart

[royer_guerra@hotmail.com]

Yes, I restarted amavis and postfix more than 3 times, and still continue... only for some domains appears that error.
