Hi, I have a plesk 11.5 panel on a centos linux dedicated server. If I create an account in the normal way and go to the mailbox, everything is ok and I can set any size quota that I like but when I migrate my vbulletin forum from a Cpanel server and go to the mailbox it says the default mail limit is 0kbs? ...and if I try to set a custom amount it says I can't have more than the default, which is zero?? How to I rectify this?
