A concern that I have is:  Do you have more than one / enough SMTP
server processes?  If you get hit with a scad of spam, each one pausing

I agree.  It's highly annoying to conduct business with someone, and
while you're chatting with them on the phone, waiting and waiting, and
waiting, for that e-mail they sent /some/ time ago, the goodwill dries
up.

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
