You don't want to suppress duplicates, you want the suppress the
unwanted copy. This is easy in most cases: make the mailing list
software not suppress duplicates, then use the following sieve recipe to
filter all duplicates:
if header :contains "List-Post" "postfix-users@postfix.org" {
fileinto "Postfix";
stop;
} elsif address :is ["To", "Cc"] "postfix-users@postfix.org" {
fileinto "Duplicates";
stop;
}
Then use reply-to-list for all mailing lists. Haven't found one that
didn't work.
NB The first line, which detects a mailing list copy, might need
tweaking depending on the mailing list software. But each mailing list
is easy to identify based on some kind of header (combination).
