Following up on my previous comments about greylisting, I

have been having issues with the gld daemon timing out and leaving lots of dead

processes.  This doesn’t stop mail from

passing through but will pose a problem in the future.  I tried to contact the authors with the issue

but as of yet have had no reply.  In an

attempt to find some resolution I dropped a message in to the postfix-users

mailing list describing my problem—I had a few responses all telling me that

they have had the same issue and have moved to using policyd.  I’m currently configuring the installation

and will report on my findings later.
