I have a reverse mail tracking feature enabled that tracks emails sent out
from orcaware.com and adds entries to the Greylist db to allow recipients of
the email to reply and be let through the Greylist immediately.  I've watched
the Greylist logs and it added an entry for each recipient on the mailing
list, so hopefully, this shouldn't be an issue.

The only issue is if the list doesn't get a single email for a 36 days,
then all entries are lost.

$reverse_mail_tracking = 1;

I think with the reverse tracking feature, the amount of traffic won't
matter.  After one email is sent to the list, hopefully, all replies
will be accepted immediately.

Best,
