Filter rules

[Ladislav Slanina]

Hi everybody.

Can someone give me a link, please, where I can find more info about mail 
filter definition? I need to send cut of first 80 letters of all incoming 
messages to another address from user account. Can I use announcement rule 
with some parameters for this purpose? Exist some more detailed Sieve 
documentation? At web I found just some very base info. Thanks for help.
