The least likely (but probably neds to be investigated first) is that it's some sort of wierd problem with your firewall that is blocking outgoing Port 25 messages. The other, more lkiely issue is that with your new connection , your ISP is blocking outgoing port25 connections, other than to their own server. If you're using sendmail, then you can set the Smart Relay Host to be your designated ISP SMTP server. # "Smart" relay host (may be null) DSmail.my-isp-name.net Other mail servers can also be set in a similar manner. The other way to test this is to use iptables to redirect outgoing SMTP connections to go to your ISP's mailserver instead of wherever they would normally go... You can also use this to test the problem -- if the patch works, then you should do the work to configure your mail servers properly... iptables -t nat -I OUTPUT -m tcp -p tcp --dport 25 -j DNAT --to-destination 10.11.12.13 (( replace 10.11.12.13 with the IP address of your ISP's mail server )) nslookup mail.myisp_name.net should probably get you a workable ip address.
