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 .... :\
