The solution to this that I have just deployed here is "greylisting". I 
have set the delay time to 10 minutes, and the whitelist-remember time 
to 32 days. No-one notices the 10 minutes delay on the first email in a 
conversation, and 32 days means that the monthly email reminder messages 
from mailing lists are whitelisted.

My users are *really* fussy, and I ran a trial of greylisting for a week 
with a few selected users who opted in to the trial. I purposely didn't 
tell them what I was changing so I could run a proper blind test. Not 
one of them noticed the 10 minute delay time. So I have just deployed it 
out to all 2000 users I have, and there have been no complaints at all.

It has got rid of the single-image stock adverts completely.
