Hi

Is 8ta actively blocking port25 outgoing?

We had some issues in setting up an application to email us on port25 (standard SMTP).

However, when I do a telnet smtp.gmail.com 587 it connects 100%.

The app does not support using TLS or SSL for email, so we're stuck with port 25 for now, or until we can get the developer to add SSL/TLS functionality...

I haven't had issues in the past using smtp.saix.net as my relay. Haven't checked in a while as the ADSL has actually been pretty stable :)

port 25 is used for server to server relays (or supposed to be used for server to server relays)

most ISP's intercepts port 25 traffic and routes it through their own servers to cut down on the number of spam/viruses through their network

if you use your own email server (like I do) you'd be better off using the actual SMTP port for this kind of thing, which is 587, because it makes authenticating to your own server easier (it doesn't try to authenticate to the proxy that is intercepting port 25, and bombing out)
