Severity: important

Every once in a while, my internal caching DNS server screws itself over.
Consequently, the mail server, which does DNSBL lookups through that server,
refuses to accept any mail, giving a 451 response.  When I notice and reset the
DNS server, the mail server accepts connections again.[0]

Then, when murphy tries the messages again, it sends many connections at once.
Sendmail, as an anti-DOS measure, rejects most of these connections.  Hence,
murphy queues a large amount of mail destined for me for a very long time.

I would like to get queued mail sooner, and I'm sure you would much prefer that
mail did not sit in the queue for longer than it had to.  Thus, my request is
that, in compliance with the RFCs, murphy should send several mails per
connection.  This will speed delivery and reduce load on my server.


[0] I understand the server should not do this (TM), but I am not yet
sure of the cause of the problem, although I think I know.  However,
this is not the point.
