Hi Chris 
I'll still try to help you , even while are some behaving as if a wasp has stung them on the arse.;-)

the pipe command means to pass process to an external program . I was using Claws mail until recently , but 
changed as 
the exchange between my mail providers IMAP server and CM kept hanging.

If I understand your problem correctly you have multiple mail accounts, probably the one supplied by your ISP 
and one from MSN 
tied to a windows installation.
If that is the case, the simplest solution is to forward the mail arriving in to your MSN to the mail account 
supplied to you by your ISP.
That way you can just use the ISPs IMAP server to get all your mail. Don't forget on the forwarding setting 
in MSN to deleted the original
 message once forwarded, unless you want a back up. You should end up with no duplicates then.

The problem with using a filter to delete duplicate messages from multiple sources is the only part that will 
be the same is the body,
 the headers will be different, only the size of the body will be the same, but only listed in the headers by 
size.
So you could end up deleting wanted messages just if the message size was the same.
Hence to compare to files, just the body of the message, you need to check it bit by bit, the unix/linux CLI 
utility for that is "diff"
There are two other utilities you need to use, SED and AWK for cutting and selecting parts of the message 
including the headers.
Google for tutorials on SED and AWK.  Mastering those will enable you to do a lot. Also look at tutorials on 
GREP.

Another example of duplicate messages with different senders, applies to most of the SPAM received, identical 
message bodies.


So although you can externally filter messages to find duplicate message bodies, its more efficient to stop 
the duplicates at source.
I've tried Chris to put this as simply as I can so you can understand it.

No doubt another wasp will fly up someones lederhosen and produce another page of 
criticism.
