They did not bother to read the email.

I'm sorry, but have you ever used qmail as a server? It delivers a bounce
called QSBMF, and to my knowledge is the only MTA that does. The bounce has
4 parts, a short intro paragraph, one or more recipient paragraphs, a break
paragraph, and a copy of the original message. The recipient paragraph tells
you why it was bounced, in human readable terms. e.g "Sorry, no mailbox here
by that name." BTW, qmail does not impose mailbox limits. Your ISP must be
using some associated program.


Succeed in spite of management.
