    and most interesting .... seems the problem is probably with openssl 
client or gnutls-cli on CentOS 5.3.

    From the same Fedora 8 box i done the previous tests, i pointed 
gnutls-cli to my CentOS 5.3 box with dovecot 1.2.5 and the zlib logging 
patch. And i have:

- Version: TLS 1.0
- Key Exchange: DHE RSA
- Cipher: AES 256 CBC
- MAC: SHA
- Compression: DEFLATE


    from maillog:

Sep 28 18:36:54 correio dovecot: imap-login: Login: 
user=<mail at box.com.br>, method=PLAIN, rip=189.11.xx.xx, 
lip=200.140.xx.xx, TLS, TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 
bits) zlib compression

    so, it seems server has the needed support for compression on TLS 
connections. Despite of that, connections from Thunderbird 2.0 and 
Windows Live Mail does not requests compression .....
