Hi !
After installing ssldump, I could compare windows xp and windows 7 clients
STARTTLS negotiation.
While the windows 7 used TLS_RSA_WITH_AES_128_CBC_SHA via TLSv1/SSLv3
Windows XP output is
New TCP connection #1: 10.0.0.252(5000) <-> my.server (25)

So how can I enable SSLv2 support ? Is it on openssl or sendmail ?
Any help appreciated.
Thanks and regards
