However, this issue is controversial on mailing lists so a lot of people including myself always hit 'Reply to All' when posting to be sure it goes back to the list regardless of whether the Reply-To: is rewritten or not. This has the sometimes-undesired effect of also sending a duplicate copy directly to the previous poster.
The following simple procmail rule will eleminate duplicate messages.
:0 Whc: msgid.lock | formail -D 16384 msgid.cache :0 a: duplicates
they get dropped in the duplicates folder /dev/null delivery is of course alo an option once you've decided it works.
