RE: [gentoo-user] Postfix receives OK, but won't send to internet

Title: Message

Your ISP may be blocking port 25 outside of their own network.   Most likely you need to configure postfix to relay mail through your ISP’s mail server rather than just use your own.   A lot of ISP’s do this so they don’t have to handle complaints about spam originating from one of their users.     -----Original Message----- From: Sean Lester [mailto:[EMAIL PROTECTED] Sent: Thursday, September 22, 2005 4:07 PM To: gentoo-user@lists.gentoo.org Subject: [gentoo-user] Postfix receives OK, but won't send to internet   Greetings,      I have a partially working Postfix installation.  It delivers messages on the localhost.  It'll receive messages from the internet.  But, it will not send messages to any hosts on the internet.  I've checked my iptables and port 25 is open both ways.  Also, each error I've gotten has been that the target smtp server has "Timed Out."  Can anyone point me in the right direction?  Postfix?  Firewall?  Host or Domain Name resolution?  Other?    Thank you for your time.
