Would someone like to test to see if QMT's implementation of SMTP/TLS

This has been discussed on the dovecot list recently, and Timo reports
that dovecot does not have this problem.


Eric S,

Here's the output. It may not look good.

[root@poweredgeT1052 apps]# ./openssl s_client -quiet -starttls smtp
-connect localhost:25
250 AUTH LOGIN PLAIN CRAM-MD5
250 flushed

EricB and has done some further testing as well, and it appears that
both spamdyke and qmail-smtpd suffer from this ailment.

Is there anyone here with any C savvy? If you do and you'd like to
have a stab at this, please chime in.

I'm going to post this on the spamdyke list, and see what Sam has to
say about it. I expect he'll be getting it fixed fairly quickly.

Eric S.,

"Depends on your spamdyke configuration settings, but if it's 'stock'
(tls-level=smtp), then it is."

Is the setting 'tls-level=smtp" supposed to be in
/etc/spamdyke/spamdyke.conf ???
It wasn't on my server. I added it with the same results.

Eric B.

It's in the present qtp-install-spamdyke script. You must've upgraded to v4.x between 8/08 and 11/09, when I added the TLS parameters to spamdyke's config.

Which spamdyke version are you running? You really should have the latest (4.0.10). qtp-install-spamdyke will upgrade your existing version. To have it create new configuration files, remove your existing spamdyke binary file before running the script (and rename/backup your configuration directory). You'll need to do that with qmail stopped.
