Sending mail in batches & how to direct crap-posting to /dev/null

[Johannes Gronvall <joha @ damicon . fi>]

Peace,

I was wondering if it's possible to:

1) Make majordomo make postings in batches..like 4 times a day?
I mean can majordomo collect new postings and then deliver them
to receivers at once few times a day?

2) Direct postings containing specified strings (RCPT in subject
in my case) to /dev/null?
