The command I used was:
gnutls-cli --protocols NORMAL:+COMP-DEFLATE --insecure -p 993
I have tried the --comp option, but it always fails for me (ubuntu 8.04)
gnutls-cli (GnuTLS) 2.0.4
Redhat is 5.3 Freebsd is 6.3

And DEFLATE gives the exact same error? LZO isn't supported by OpenSSL.
yes ... error from DEFLATE and LZO are exactly the same on gnutls-cli output and maillog on the CentOS 5.3 box.
Well, not the same server but looks like this one works too:
gnutls-cli --priority NORMAL:+COMP-DEFLATE -p 993 secure.emailsrvr.com
And just for fun I tried imap.gmail.com, that didn't support compression.
i had tried imap.gmail.com too :)
interesting findings ..... from CentOS 5.3, i cant get any compression method to work:
[root@correio dovecot]# gnutls-cli --insecure -p 993 -p 993 secure.emailsrvr.com --comp LZO DEFLATE NULL [ ......]
Version: TLS 1.0
Key Exchange: DHE RSA
Cipher: AES 256 CBC
MAC: SHA
Compression: NULL
but from a Fedora 8 box:
[root@correio ~]# gnutls-cli --insecure -p 993 -p 993 secure.emailsrvr.com --comp LZO DEFLATE NULL [ ......]
Version: TLS 1.0
Key Exchange: DHE RSA
Cipher: AES 256 CBC
MAC: SHA
Compression: DEFLATE
and Fedora 8 OpenSSL is even older than CentOS 5.3 one:
CentOS 5.3: [root@correio dovecot]# rpm -qi openssl Name : openssl Relocations: (not relocatable) Version : 0.9.8e Vendor: CentOS Release : 12.el5 Build Date: Fri 04 Sep 2009 09:33:56 AM BRT
Fedora 8: [root@correio ~]# rpm -qi openssl Name : openssl Relocations: (not relocatable) Version : 0.9.8b Vendor: Fedora Project Release : 17.fc8 Build Date: Mon 15 Oct 2007 07:56:22 PM BRST
probably there's some build option on CentOS that is disabling compression. If 0.9.8b on Fedora8 built in October/2007 can do it, so 0.9.8e on CentOS 5.3 built on September/2009 should be able to do it too ....... oh boy, i really hate those weirds compilation options from Redhat .... :\
