Ntlworld SMTP issues on Three network

Hi all,

Over the last few months I've had issues sending emails when I'm out and about using the Three mobile network. When I'm at home and on wifi there is no issue. 

I'm using a ntlworld email address, smtp.virginmedia.com server and port 465.

What could be the issue?

Re: Ntlworld SMTP issues on Three network

Seen it recently here:

If your Three IP address is being blocked because the shared IP address is on Spamhaus's SBL CSS blocklist there is not a lot VM will do for you. The policy may be harsh when it comes to shared IPs but it is the policy.
