Disable reputation filter based on LDAP group query

Unanswered Question
Jun 5th, 2008

Is it possible to completely disable the reputation filter based on whether the recipient is in a certain LDAP group?

I'm currently thinking no as LDAP groups are assigned a message filter and by this point in the pipeline the reputation filter has already been applied.

Perhaps someone more experienced can confirm/disprove this for me?

That's correct, senderbase reputation filtering occurs very early on. At the IP/TCP level of a connection. To get more info on this, check out the user guide on HAT Overview.

Since senderbase reputation filtering occurs early on, even before the mail-from/rcpt-to/subject information are obtained, it is too late to enforce LDAP settings.

However, what you can do with ldap is verify if the sender or recipient are a member of a certain group and then disable anti-spam/anti-virus/content filtering from their email. You would use ldap-from-group in conjunction with incoming or outgoing mail policies.

To make an email immune from senderbase reputation filtering, you would need to know the IP/hostname/partial hostname of where their message is coming from and add that info to the whitelist sendergroup in the HAT overview.
