Rejected - TRUSTmanager

Post by Sarem »

Hi everyone,

i have a problem, when I try to send mails to a specified mail server.
We have an /27 IP range and I have tested multiple IP addresses and get the same problem.

<[email protected]>: host mx01.gisa.de[194.113.77.190] said: 550 5.7.1
<[email protected]>... Rejected - TRUSTmanager (in reply to MAIL
FROM command)

I think, it's a blacklist problem. Have You any idea?

Best regards

It is possible that the recipient's email provider is using a filter called "TRUSTmanager" - you might need to contact the recipients by other means and ask them why or to ask them to whitelist you.

The good news is that the IP address in the rejection message shows "clear" on the blacklists checked by the WhatIsMyIpAddress blacklist check page.

A check at multirbl.valli.org showed a listing at RFC-clueless, which it seems to have inherited from its predecessor, the now closed RFC-ignorant list.
