memailfilter_usr.exe Is this an error that anyone is familiar with? I've not yet begun to dig to deep in, but I am noticing this error on multiple occassions in my error logs. COM Error 800A0BBA (Unknown error 0x800A0BBA, File could not be opened.) at execute "C:\Program Files\SWsoft\Plesk\admin\bin\memailfilter_usr.exe" somedomain.com raffi DBFAD26C502141CAA82BC05EFAA05C.MAI at (vconsoleapp::run line 138) Execute file name: C:\Program Files\SWsoft\Plesk\admin\bin\memailfilter_usr.exe I don't know that this has caused a problem that I have run across thus far, but I am trying to prevent it from becoming one? Seems indicative of a permissions problem, but which permissions is beyond me. Any ideas?
