Milter-greylist

Dear List Readers - 
 
I have run into a problem, possibly because of my noobiness with this
milter, but i installed this on my mail servers over the weekend, and it
does seem to do the trick...however i started experiencing a total lack
of mail delivery even though i manually whitelisted maillist domains,
etc, NOTHING was being delivered, except in very very small spurts. So,
i disabled it, turned it off, and removed it from the sendmail.cf and
restarted sendmail - THREE DAYS LATER, i am still seeing delays and
non-deliverability to my MXs. 
 
What did i do wrong? Has anyone else seen this? Anything i can do to fix
my problem? I have 2 users on my domain that have gotten very little of
their daily email and they are wondering where the hell it went, LOL...
 
Any help would be greatly appreciated.
 
Thank you in advance
Michael Weiner
