memcache: IP & helo

[Tom Kinghorn]

Good afternoon list

In Postfix, is it possible to use memcache to store IP & helo infomation 
for a helo_access ?

We receive alot of spam from a single IP address using multiple helo's.

I would like to check the helo name against the memcache entry.
If it does not match, then REJECT / DISCARD.

Thank you in advance.
Tom
