smtp ESMTP server not available (blacklisted by local policy), IP: 84.92.108.193

Hi tech team, looks like I've been IP blocked from using the plus.net outbound SMTP relay, likely as a result of a an email account getting breached on my system and used to relay junk through my mail server. I've done a direct check with telnet and get rejected immediately with the above message. First time I've had this happen in 30 years!

 

Firstly - apologies, I've hopefully closed the hole that was being used (an SMTP login credential) and adjusted my fail2ban settings to reduce opportunity for password spraying my SMTP server. I'll also check with the user concerned (my son) and ensure his client device(s) appear clean and that he hasn't been phished. He'll need to update his password too as I've locked the account.

Secondly - can someone please check my assumptions above and unblock my IP please?

 

Thanks, Phil.

Yay! this has now been silently actioned.. happy to have outbound email back again (after 2 weeks!), not so impressed by the complete lack of feedback on either this post or the ticket (232173519) that was assigned once I called this in.
