Hi,I'm trying to add different domains to be bypassed by antispam filter in our Exchange server, but it keep saving only the last one, and overwriting the others. Same is happening with individual users. I'm using Exchange 2007 in typical installation without Edge involved.Thank you for any help.alfa21

How are you trying to add the domains/users? EMS?

I'm using EMS for it, example:Set-ContentFiltering -ByPassSendersDomain: microsoft.com (command may have mistakes, because I'm out this moment, and I cannot remember). If I add another domain: Set-ContentFiltering -ByPassSendersDomain: google.com, it'll overwrite microsoft.com.I don't know whether possible to add like:Set-ContentFiltering -ByPassSendersDomain: microsoft.com, google.com,...Thank youalfa21

Try this syntax.Set-ContentFiltering -ByPassSendersDomain ("microsoft.com","google.com",...)

After checking on detailed help on EMS, it has to be like:Set-ContentFiltering -ByPassSendersDomain: microsoft.com, google.com,...And, apparently everytime we need to add another domain to that filter, we need to add again domains already included, and maximum is 800 domains.alfa21

Try this:$a = get-contentfilterconfig$a.ByPassSendersDomain += "microsoft.com"$a | set-contentfilterconfig
