Exim is up and running but is not reachable on port 25 as smtp server.

The pop on port 110 is working, but that is handled by the vm-pop process i thought

The port is open in the filewall, and the exim config file is almost out-of-the-box (antivirus was added long ago).

Maybe it has something to do with the local ethernet (eth1) adapter that was added a while ago?

I don't know where to start. I started with telnetting to port 25, but this was unreachable somehow. I checked exim panic and main log without any success (nothing special in there).

Could someone point me to where the problem might come from?
 
You said you had tried to telnet to port 25, were you telneting from your workstation or from within your server?

If you tried to telnet to port 25 from your workstation only, you should also try to telnet port 25 from your server locally to see if it is a networking problem or problem on the server itself.
 
Thanks alot for the reply.

It's actually quite strange. I can telnet to it from localhost and from another server which is within the same rack.

Those two are both connected throught an internal network as well (eth1). This isn't causing the issue however, because when i disabled it the eth1 adapter the second server was still able to connect to it.

It's not an issue of my workstation either, since i tried it from two locations.

And the weirdest thing is that the pop port (110) works normally, but port 25 can't be connected to.

Any more things i could try?
 
I think i figured it out, i did some intiuative googling and came by the following article http://www.webhostingtalk.com/showthread.php?t=521846

If what david510 doesn't work, then check if your ISP might be blocking port 25. Lots of ISP's are blocking port 25 these days in an effort to reduce spam. If your ISP is blocking port 25, like mine does, here's a quick workaround:

I tried to connect through the port normally reserved for smtp ssl connections (587) and it works.

Probably my isp is blocking port 25.

Thanks alot for helping me.
