[Bug 1001040] Re: "TLS library problem" drops incoming mail when sender uses RC4-MD5 cipher

Today I upgraded to postfix 2.9.3-2~12.04.1.  I can't tell whether or
not I am still affected by this bug.

I have commented out from main.cf the temporary workaround that I have
been using since the problem first appeared in May 2012
("smtpd_tls_exclude_ciphers = RC4-MD5").

I have sent myself three test emails from Gmail, but on none of these
emails has the sender tried using the RC4-MD5 cipher.  (All three have
used ECDHE-RSA-RC4-SHA .

Scott (or others): Is there a way I can configure postfix to accept
*only* the RC4-MD5 cipher?  I'm willing to change my postfix
configuration to something goofy for a few minutes so that I can send
myself another test email.
