Checking if gmail address is blacklisted?

Hi there,

Not sure if this is in the right forums, but is there a tool that will check if a gmail account is blacklisted?

Thanks

How are you sending the emails, and do you have control of the mail server that’s sending them?

No, it’s just going through my normal gmail account

Have you received emails from the google servers indicating one or more of your emails has bounced?

Yes, I received a bounce back with this:

“The response from the remote server was:
554 Transaction failed Reject due to policy restrictions. For explanation visit http://postmaster.gmx.com/en/error-messages?ip=209.85.210.53&c=hd

and have you visited the link you were given, opened the three matching results to the message you were given, and followed the instructions given?
