Hello all, I am running: OS CentOS 6.3 (Final) Panel version 11.0.9 Update #14, last updated at Sept 19, 2012 03:47 AM My problem happens when a client goes in to their panel and chooses "Switch on spam filtering for this e-mail address" in the Mail tab. It fails with this error: "Only %available%% unique e-mail addresses can be added." Needless to say, Googling doesn't turn up anything for this. It does turn up a possibly related issue (http://kb.parallels.com/en/5640) where SA is/was limited to 100 entries by default. The client certainly doesn't have 100 users and this isn't a black/whitelist but just for grins I removed spam filtering from another address and tried to add spam filtering to the original address but got the same error. After this I was able to re-add spam filtering to the original address so it doesn't seem like this is a numerical restriction. Has anybody seen this before? Any thoughts on how to fix? Thanks in advance!
