Title: Aftter Update, mail server is not working
Post by: labpros on 2015-04-14, 12:10:44: Hi, aftter Update,
mail server is not working. The mail client can not connect to the server. This is the message of the thunderbird
"Sending of message failed.
The message could not be sent because the connection to SMTP server mail......com timed out. Try again or contact your network administrator."

Post by: MRatWork on 2015-04-14, 12:24:06: Better inform 'sh /script/sysinfo' before asking.

Did you run 'sh /script/cleanup' after update?.

Post by: MRatWork on 2015-04-14, 14:10:35: Try disable first with 'chkconfig iptables off; service iptables stop'. Next times, you can enable with 'chkconfig iptables on; service iptables start'
Title: Re: Aftter Update, mail server is not working
Post by: labpros on 2015-04-14, 14:31:37: I have stopped the firewall service but the problem still exissts, it looks that the 25 port is blocked somehow, but i can send a message by changing the port from 25 to 587.

Any thoughts??
Title: Re: Aftter Update, mail server is not working
Post by: MRatWork on 2015-04-14, 14:34:21: Check for open port with 'netstat -lnt'.
Title: Re: Aftter Update, mail server is not working

Post by: MRatWork on 2015-04-14, 14:46:44: Another possible is your provider block certain ports.
Title: Re: Aftter Update, mail server is not working
Post by: labpros on 2015-04-14, 19:00:30: Finally it was that, the provider had close the port 25 trying to reduce spams
