Jonesy's are being treated as spam:

host gmail-smtp-in.l.google.com[74.125.70.26] said:
    550-5.7.1 [108.166.152.50      12] Our system has detected that this
    message is 550-5.7.1 likely unsolicited mail. To reduce the amount of spam
    sent to Gmail, 550-5.7.1 this message has been blocked. Please visit

However, they're not showing up in the Web-based spam folder GMail provides.
I have no idea why his emails are being singled out (because sending domain info
in the header calls out three separate domains, maybe?)

Emails from other apparently-legitimate sources are being rejected on "security"
grounds:

The possible solutions that occur to me are three:

1. Whack GMail over the collective head with a blunt instrument until it behaves 
  itself (good luck on that)
2. Have the list mailer check for key phrases in bounce messages and ignore
  them if they're found
3. Increase the list mailer's bounce tolerance to 5-10 messages, and have
  affected users use a filter to auto-trash the messages unread.

I'm pretty sure I've been unsubscribed without noticing (because I do auto-trash
the "threat messages") at least once--that would have been around April 1 of last 
year.
