Hy all. I have installed centos 5 with postfix and dovecot (perfect-server-centos and virtual-hosting-with-virtualmin-on-centos5) and webmin/virtualmin. I can't send or receive mails and I don't understand why. One year ago I made two servers like this one and all worked very all. telnet 94.177.41.70 110 Trying 94.177.41.70...

Did you enable "Server requires authentication" in your email client? Also, do the MX records of your domains point to the correct server?
Thank you falko. I had to change the hdd, so i reinstall centos and all the servers. Now I can receive emails in webmin or outlook but I can't send. When I want to send from webmin or pommo interface the emails remains in the Postfix Mail Queue (Mail Queue1 messages) and is never sent. I don't understand why. Dovecot instead works just fine. What is wired now is that ehlo localhost doesn't work. Yesterday were just fine. telnet 94.177.41.70 25 Trying 94.177.41.70... Connected to xprivatecams.com (94.177.41.70).

I can sent only email on localhost from user to user. Dovecot works just fine on outside: Jan 17 23:46:54 xprivatecams postfix/smtpd[4289]: connect from vds-00438.limehost.ro[93.114.42.63] Jan 17 23:46:55 xprivatecams postfix/smtpd[4289]: 1AD17A80019: client=vds-00438.limehost.ro[93.114.42.63] Jan 17 23:46:55 xprivatecams postfix/cleanup[4298]: 1AD17A80019: message-id=<[email protected]> Jan 17 23:46:55 xprivatecams opendkim[2776]: (unknown-jobid): vds-00438.limehost.ro [93.114.42.63] not internal Jan 17 23:46:55 xprivatecams opendkim[2776]: (unknown-jobid): not authenticated Jan 17 23:46:55 xprivatecams opendkim[2776]: 1AD17A80019: no signature data Jan 17 23:46:55 xprivatecams postfix/qmgr[2554]: 1AD17A80019: from=<[email protected]>, size=1187, nrcpt=1 (queue active) Jan 17 23:46:55 xprivatecams postfix/local[4300]: 1AD17A80019: to=<[email protected]>, relay=local, delay=0.2, delays=0.18/0.01/0/0, dsn=2.0.0, status=sent (delivered to maildir) Jan 17 23:46:55 xprivatecams postfix/qmgr[2554]: 1AD17A80019: removed Jan 17 23:46:55 xprivatecams postfix/smtpd[4289]: disconnect from vds-00438.limehost.ro[93.114.42.63]

I'd ask your ISP. also make sure that your server isn't blacklisted: http://mxtoolbox.com/blacklists.aspx
Listed 0 times with 3 timeouts. OK - 94.177.41.70 resolves to 70.41.177.94.netvisiontelecom.ro Warning - Reverse DNS does not match SMTP Banner 0 seconds - Good on Connection time Not an open relay. 1.201 seconds - Good on Transaction time Sounds good
I asked my ISP, they don't block port 25. so this is not the problem. What can it be? I don't know what to do else. Maybe if I transform it to an open relay for testing ?
IS mail.flabell.com your own server, or is it a remote one? What's the output of Code: netstat -tap and Code: iptables -L ?
