O2 IP blacklisted / cannot connect to corporate Email

[Anonymous]

O2's IP assigned to me is blacklisted on Spamhaus ZEN

https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a82.132.212.115&run=toolpage

resulting in my Company's SMTP server rejecting me sending email because it uses that blocklist. Can an O2 network Admin please look into this? I am a paying customer since many years and can expect 02 Admins to do their homework and provide users with a clean IP address...

My Broadband IP is also listed as on 2 lists by the tool, one ZEN and one RATS.

It is possible the lists used by these registries are out of date.

I would take the issue up with your company's mail system admin, as ip address blocks can change hands rapidly and what once was bad is no longer so. You may wish to investigate using VPN to mask your ISP (O2) IP.

Good luck.
