Post subject:  MAIL.COM is blacklisting my server


For some reason this ISP decided to blacklist my IP 48h ago.

This includes emails trying to get delivered to:

All I can get is:
Action: failedDiagnostic-Code: smtp; (mxgmxus007) Nemesis ESMTP Service not available 554-No SMTP service 554-IP address is black listed.  

I tried to contact the ISP by email on their website but didn't get any response yet.

Luckily there is a human on the other end!

Dear Sirs,

thank you for your query.

After having reviewed the issue and the actions taken, we have now removed your IP address from our blacklist.

Our servers will be updated within the next hour. You will then be able to receive emails from this sender again/send emails to our system again.

Many thanks

​GMX MailSecurity

... and GMX is blocking me again.

So. Much. Fun having to explain again their rejection tests are wrong.
