    got it .... so, basically, i shouldnt be using .gz at all, is that ok ?

    i understood that, when moving from new to cur, filename should be 
appended of ':2,'. But filenames on new, as i understood, should never 
be changed. As soon as they are read there (on new), they should be 
moved to cur.

    what would be the correct way of compressing messages on the new 
directory and adding the Z flag ? Would be any problem if, when 
compressing on new, add the ':2,' suffix ? Indeed it would be ':2,Z' 
suffix one

    i tried it ...

gzipped the file 
new/1263462832.V6814I43300c8M993425.correio.domain.com.br,S=10137
and got the gzipped file to be named
new/1263462832.V6814I43300c8M993425.correio.domain.com.br,S=10137:2,Z
and excluded the original file

when checked mail, file was correctly moved to cur
when replied to that mail, file was correctly renamed to
cur/1263462832.V6814I43300c8M993425.correio.domain.com.br,S=10137:2,RSZ


    is that OK to have filenames on new with the ':2,Z' suffix ?
