CentOS 5.x | SendMail

I'd like sendmail to use a specific cipher when negotiating a TLS session with a specific remote MTA/domain. Is that possible?

I'm aware that a minimum bit strength can be added to the TRY_TLS: parameter in /etc/mail/access but wasn't sure if a cipher could be used here or not.

Why the down vote? I tried checking Google and prior SF questions before asking. –  Mike B Jan 2 '13 at 23:30

I think I figured this one out:

1) Add the following lines to /etc/mail/sendmail.mc:

LOCAL_CONFIG
O CipherList=HIGH:!<CipherNotToUse>

2) Restart SendMail:

/etc/init.d/sendmail restart
