Unless you limit the number of connections to each recipient host, you risk taking an email server hosting a large number of monks to its knees.

Qmail is a very good internal system. I have stopped recommending it for external mail servers a long time ago. The internet infrastructure is just not resilient enough against a server like this that could present a very effective denial of service attack.

This is from someone who was involved with qmail use and advocacy very early on. One of my first public perl scripts is in fact still being distributed (search for Brian T. Wightman on one of the qmail pages), although I no longer recommend its use - the SMTP world has changed :).

The tomes, scrolls etc are dusty because they reside in a dusty old house, not because they're unused. --hangon in this post

    Maybe a silly suggestion, I'm no SMTP expert...

    What if 58 trusted monks around the planet would send 1000 emails each?

    We could start a group "Mailsender" where these monks could join, and they would get the required lists and email for qmail.

    Personally I would suggest that each should send 3x1000 emails for redundancy and to guaranty a high likelihood of deliverance.

    The email-text of each Mailsender should somehow differ to avoid spamfilter but should be a forward of perlmonks.

    This Mailsender group could be quickly reactivated in the "next incident"... ;)

      You're right, that won't work. That was early spammers trick, the ISP learn to fight long ago.
