And DEFLATE gives the exact same error? LZO isn't supported by OpenSSL.

do the IMAP4 server you tried is remotely accessible so i can try 

from a different machine ? Maybe we're dealing with some client lack of compatibility and not server one ......

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.
