Hello guys, I do not know how it is posible : *vi /etc/postfix/main.cf* # INTERNET HOST AND DOMAIN NAMES # # The myhostname parameter specifies the internet hostname of this # mail system. The default is to use the fully-qualified domain name # from gethostname(). $myhostname is used as a default value for many # other configuration parameters. # #myhostname = host.domain.tld myhostname = mail.hlacik.eu *service postfix restart* [root at sx1 postfix]# postconf -d myhostname *myhostname = sx1.labs.hlacik.eu* What is wrong?? I have Centos5.2 with latest updates. D. -------------- next part -------------- An HTML attachment was scrubbed...
