    When i created this thread, some weeks ago, i have also made some 
tests with recent versions (OpenSSL, dovecot, Thunderbird) and couldnt 
get compression.

    I didnt any kind of tracing debug or similar, i just created some IP 
accounting rules and watchs it when downloading a know set of emails 
with a know size. There was no difference when downloading through 
unsecure IMAP or secured (TLS) IMAP. So, there's no compression being 
activated.

    When searching for that, i found that there's already a RFC for a 
COMPRESS imap extension ... as imagined, there are pretty few clients 
that supports it .... Thunderbird 3 Beta supports it .... but asking 
customers to use a Beta software is not acceptable. So, we'll probably 
need some more years to have this extensions widely deployed and 
supported by clients.
