SMTP restriction list exceeded 64K limitation

What can be done to expand the list of internet addresses in "Deny messages from the following internet addresses/domains:" or the "Allow messages from the following internet addresses/domains" beyond the 64K field limitation?

Currently we are using Domino 5, and we do not have immediate plan to migrate to R6.  Any ideas?

    Use groups.

    Create several groups, and put those names in the "Deny message..." field.

    Note: same limitation exists in R6

    For SMTP Inbound Intended Recepients controls, the field Allow messages only for the following internet addresses does not allow Group entry - meaning that Domino is unable to check for individual list in the Group.  It just wont work. This is where we are having problem.  Any other ideas?

    You don't really ever need to use both ALLOW and DENY.  If you use ALLOW, then everything else is by defintion denied.  So why do you need this huge allow list?! I know, I know, you want to block out spam addresses, except for teh legitimate names you know in those domains.  That's an impossible scheme, you can't keep up.  Just implement the R6 DNS blacklist. You don't have to upgrade your whole domain -- just upgrade the SMTP gateway and teh address book.
