All my users on the server can not recieve mail. they can send mail out from there account, but can not get mail. They always get Remote host said: 554 mail server permanently rejected message (#5.3.0) I honestly dont understand why. Nothing has changed on this box. The only thing that was done was upgrading from 7.5.3 to 7.5.4 Is there something that changed that is now blocking all mail on this box. psa-qmail 1.03-fc2.build75050824.12 psa-qmail-rblsmtpd 0.70-fc2.build75050824.12 Please let me know if there might be any other info that you would need. I just cant figure this out and its starting to bug me.. Thanks for any help.
