Dynamic Distribution Group LDAP query issue

Thanks to any and all in advance for your help.

So I'm trying to configure a dynamic distribution group query to accomplish two things:

1.  Grab all mailboxes with secondary email addresses of say @domain1.com and @domain2.com

2.  Exclude Distribution groups in the query (as some of the distribution groups have secondary addreses as above)

I'm running the following powershell to set the recipient filter on the DDL:

Set-DynamicDistributionGroup "DistributionGroup" -RecipientFilter {((EmailAddresses -like "*@domain1.com") -and (EmailAddresses -like "*@domain2.com")-and (-not(RecipientType -eq "MailUniversalDistributionGroup")))}

After checking the members of the dynamic list, I'm still seeing regular distribution groups be included when the Dynamic Distribution List is populated.

Banging my head on my desk.  What am I missing?

Thanks again!
