Dupes and Dates

Here's how you get rid of duplicate email..

at the beginning of your .procmailrc:

:0 Wh: msgid.lock

formail -D 65536 $HOME/.msgid.cache


Creates a message-id cache with up to 65k of message-id's for cache..
eliminates dupes.. seeing an average message-id is 45 chars or so this
will give you a cache of the last 1456 e-mail msg-ids.

That's from the procmailex man page by the way. Everyone should be
required to memorize it. Nesting rules rock.
