Is port 25 block?

Hi,

Does anyone know if port 25 is blocked? I'm trying to run my own SMTP server but emails are no long being sent out.

I used to be with Velcom but I have recently switched over to a Nexicom DSL login. I had no issues with sending emails directly from the SMTP server when I was with Velcom but since the switch I noticed emails are no longer going out.

I have an SMTP relay as a backup but I would like to know for sure if Nexicom is blocking port 25.

home connections probably yes... business connections no

Easy way to check is try to telnet with port 25 to a known good smtp server.

On a residential connection, yes it is blocked.

That is the only thing we block, but unfortunately we have no choice with the amount of compromised computers that are out there.

Yes, as bbuchana has mentioned it is blocked on residential connections - it is also blocked on business connections *however* if you have a static IP address (residential or business) then it is not blocked.

Hope this helps - let us know if you have any more questions. Or PM me your IP address (if it's static) and I can tell you if your SMTP server is reachable.

Thanks a lot for the answers! I have my SMTP relay server going through different port so if isn't an issue anymore for me, I just wanted confirmation since I couldn't find the information anywhere else.
