I have a 2mbps ADSL connection with MWeb on a new account and separately, I got a free 1GB capped account with Axxess some time ago.
When connected to MWeb's network, I'm not able to connect to any SMTP server via Outlook or telnet or any SMTP server, except MWeb's. I can, however, connect to any SMTP server when I'm connected using my Axxess account.
MWeb have assured me that they're not blocking anything to do with email but the fact remains I can't use my SMTP server when connected to their network.
An attempt to telnet into vodamail's SMTP server (solely to test the connection) yields the following:
Microsoft Telnet> open smtp.vodamail.co.za 25
Connecting to smtp.vodamail.co.za...
421 Cannot connect to SMTP server 22.214.171.124 <126.96.36.199:25>, NB connect error 1460
Connection to host lost.
Press any key to continue...
I would be happy to substitute MWeb's SMTP server in my mail setup, however, there are problems with that to do with SMTP relays I believe. See below:
