Hello,
1 of the users on my server is failing to deliver emails, all emails sent to 6 different email address are returned with this msg "550 permanent failure for one or more recipients".
First I suggested to contact one of the recipients mail administrator, but the 6 email addresses are not on the same domain name, they are 6 different companies. There must be something wrong from our side.
We tried to use another computer and another ISP without success.
and not all return messages are the same, here are some e.g.
MXtools returned no errors from my server neither from their servers.
Thank you for some hints
