Did some shoveling in the email mines and got the mail queue on vger proper down to under 1000, which is good. Average time of an email waiting to get into vger (this does not include processing on vger and subsequent bouncing back out) is under 2 minutes, with most instances being literally seconds.
Few more domains having issues, looks mostly like smaller e-mail hosts having low rate limits. I'll keep an eye on them and likely have to eject them.
