RedHat released sendmail-8.13.8-10.el5_11.src.rpm which includes sendmail-8.13.8-ssl-opts.patch which adds support for disabling SSLv3 and SSLv2 in sendmail.cf

But as far as I can see there is no support in sendmail.mc – I can’t see how to compile sendmail.mc to get the required line ServerSSLOptions in sendmail.cf

Does anyone know how to do this ?

  • Thanks. That was too obvious; I should have read more documentation. The generic advisory said to add those lines to the LOCAL_CONFIG section of my sendmail.mc, but I didn’t have a LOCAL_CONFIG section, so I assumed it was referring to a newer version of sendmail.

    Meanwhile, I made a patch for sendmail-cf and sendmail-doc back-ported from sendmail-8.15.1, if anyone’s interested.
