What SMTP ports can I use?
One of the many advantages of using AuthSMTP is that we operate our service on many different ports in the event you find you are using a connection that is blocking some of the more standard SMTP ports.
Our SMTP service is available on the following ports:
- 325 (non-SSL only)
We have a web based SMTP port checker tool which will test which ports are open from your computer to our network.
If you have any questions please contact us.
