Hi,

I have this problem with postfix.
I can receive mail, no problem. But sending won't work. The mail stay's in the queue.

I'm host e few domains on a Gentoo box (only apache) and with virtualmin it work's perfect.

Now I also want to create a few mail adresses and aliasses. That also works perfect (wen receiving mail on those adresses).

But sending won't work.

I get the message: connect to mailbackup1.kpn.net[194.151.226.36]: No route to host

When I: telnet 192.168.5.20 25 I get a ->
root@webserver root # telnet 192.168.5.20 25
Trying 192.168.5.20...
Connected to 192.168.5.20.
Escape character is '^]'.
220 gentoo.homenetwork ESMTP Postfix


So that's oké. But when I telnet trango.nl 25 I get a ->
telnet trango.nl 25
Trying 85.145.232.237...
telnet: Unable to connect to remote host: Connection refused


What can I test now to resolve the problem?

I would contact your ISP and find out if they allow port 25 (SMTP) outbound. I have heard of some ISP's canceling you if you run a Mail server from home

I host it at home. DNS record from ISP are oké.
