as was discussed some time ago, since the original poster is victim
of dictionary attacks, I would also deny any recipient after a
certain number of failures n:
condition = ${if > {${eval:$rcpt_fail_count}}{n}{yes}{no}}
Personally I would reject all recipients, also the one acceptedbefore
this condition was true, if any, by denying at the DATA phase. I
guess this is not needed once the delay is over 5 minutes...
