1. Telnet port 25 other server from your server, if connected, try rebuild postfix
2. Stop csf and maybe iptables, and try no. 1, if failed, may be port 25 closed by your provider.

hi dear all;

problem found. VPS server seller is source of problem.
they  give us only one (1) SMTP connection simultaneus. 
this company name is Contabo. note it.
