[Greylist-users] pobox servers

[Scott Lair]

Hello,

I am using pobox.com as an email forwarder.  Pobox mail is coming
from different servers.  When someone sends me an email, say john at abc.com,
greylist correctly adds it to the greylist. An hour later john at abc.com 
resends the mail, but it comes through a different mail server, so 
greylist adds that to the greylist.  This could continue happening
and the mail may never get through.  Is there a way to rewrite 
mail coming from pobox.com to always be from the same server and ip?
Making greylist a bit less restrictive might also work.  Is there a
way to do this or possibly another solution?

thank you,
