retry_data_expire option, lower from 7 days to however many seconds.

If the retry data is always going to be useless for your situation (if A
only sends mail onto B) and you have frequent problems with B, then if
you don't want to have Exim doing db updates every minute, a crude but
effective method is to nuke the retry hints file regularly.

crontab for exim runtime user:
* * * * * rm -f /var/spool/exim/db/retry

where the path /var/spool/exim should be replaced by whatever
"exim -bP spool_directory" gives you.
