I have a large announcement list (over 15k subscribers) that I'm trying to
migrate to Majordomo, and I'm getting blacklisted by several large ISPs:
Yahoo: 3066 addresses
AOL: 2346 addresses
Hostmail: 1374 addresses
I get several errors, but the most obvious one is that I'm sending to too many
recipients at one time.
mailq (postfix) tells me that I have about 8k outbound recipients sitting in
my queue, every time I try to send to the list. Begging to get off the
various blacklists only gets me blacklisted again as soon at the postfix
tries to flush the queue.
