Re: [Evolution] Check for duplicate messages

[Antonio Bemfica <antonio axolotl ic gc ca>]

This is trivial to do using procmail (by checking the Message-ID
header). You can get a bit more sophisticated and do an MD5 hash of the
body of incoming messages and store it on a database (dbtool, for
example: http://www.daemon.de/dbtool/).

If you or anyone else is interested I can post a recipe that does the
above.
