Might only be of historic interest, but Tom Kistner's "timeban"
script of a decade ago:

https://lists.exim.org/lurker/message/20060502.201702.5ae738bb.en.html

was effective for this kind of job. I remember using this with exim
after modifying the script to work with OpenBSD's packet filter.
I've probably still got a copy of this script somewhere...
