SSL TLS on SMTP

RufusToofus
Our MAIL Relay worked fine until the NEW SSL Bug fix was applied, any suggestions ??

We have upgraded to 9.210-20, we now are getting serious EMAIL rejection problems EXIM Log:

SMTP command timeout on connection from (iPhone) [85.255.233.181]:23650

    Line 257 looks a bit different here:
    tls_require_ciphers = HIGH:!RC4:!MD5:!ADH:!SSLV2
    instead of
    tls_require_ciphers = RC4+RSA:HIGH:!MD5:!ADH:!SSLv2

    So there are 2 different versions and the only difference is in the RC4-part.

    Is "RC4+RSA" needed for the solution or may it be disabled with "!RC4"?
