Basic Pleskian
Dear Forum,
Since we switched to our new mail server, operated through Plesk, some of our customers have reported message sending errors. The server returns : 550 5.7.1 Command rejected (in reply to DATA command).
I've tried first to deactivate the spam filter and everything went right. Since I want to have spam filtering, I've tried to enter the customers' domain name into Greylisting white-list: *@domainname.com. Unfortunately, mails are again rejected and it seems either the syntax is wrong, or the white-list is not processed by the spam filtering engine.
Can someone help me understanding what's going wrong there?
Thanks in advance for any help!
