Comment 1 for bug 365390

I am unable to duplicate this here in a Jaunty (rc) virtual machine.

The default /etc/postfix/main.cf file does not seem to contain an entry for smtpd_tls_mandatory_ciphers when I install postfix. I also unpacked the postfix 2.5.5-1.1 source package and do not see any obvious sign of this in there.

Please provide full details on exactly how you installed postfix, and if you were asked any configurations questions by debconf when installing, how you answered them.

I suspect that the problem here may lie in another package, not postfix itself? In particular, did you install the dovecot-postfix package?
