Duplicate recipe from procmailex doesn't work on some lists

2007-09-19 14:02:04
Hello,

I have added the standard duplicate-elimination recipe from procmailex
to my rc file (using maildir):

:0 Whc: msgid.lock
| formail -D 8192 msgid.cache
:0 a:
.duplicates/

I have noticed that it flags as duplicates many messages which aren't
duplicate at all, but often belonging to several recurring categories:
mailman notification for some lists I manage, Centos security
advisories, most messages from the Dovecot mailing list are the most
common. What can it be, why, and how to fix it?

Does the case of the Message-id header count (sometimes it's
Message-ID, others it's Message-id etc...)?

Any help is greatly appreciated!

        Marco
