When I sent a mail today to one of the accounts on our newly set up iRedMail server (using a Thunderbird mail client), I got the message back:
Cannot send mail to xxyz@mydomain.com because greylisting is in effect. Try to send the mail again later.
This is awkward because greylisting normally does not prompt any response in an email client.
Also I am not aware that there is greylisting set up anywhere and cannot find any option in the iRedAdminPro panel.
The message appears only if I try to send emails to that specific mail account.
In fact, trying from another mail server gave me the response "user unknown". But I have a mail box in iRed Mail for that user.
(I seem to remember that a greylisting option did show up in the open source panel before I installed iRedAdminPro - is there one?)
I do not want any greylisting going on. Can you help me disable it?
It might be something different, not greylisting, which is going on. Any idea where to look?
