Best bet is to use a mail relay server and do your ldap or whatever lookups to 
your exchange box from there. GFI will do it for you, there are others too.

Is there anyway to accomplish the above at the firewall - we are using ISA?  We 
are receiving ton of messages with anything left of the @.

 

Some of the recipients:

jkyxpzbjzqkli@xxxxxxxxx

lggxxtpghdx@xxxxxxxxx

jxbhwutklun@xxxxxxxxx

 

 

Is there a way to extend Recipient Filtering to the firewall?

 

TIA
