Relay Access Denied, when you backup and lock your domains

[Daniel H]

Did You try to lock your domains, when you make a backup? You have the options in the BackupManager to lock your domains during backup... I did this and before I will choose this option permanently, i tested it and send a mail from an external mailadress to me... When Domains will locked, postfix bounce this mails with an 554 5.7.1 <xxx>: Relay access denied.. WTF???

THIS IS A BIG FAIL... There should be a 4.7.1 - Service unavailable - Try again later... so for now, its not recommended, to use the function: lock domains during backup... i think, thats a bug... - psa 11.0.9 - open suse 12.1
