Old clients fail to establish SSL Connection to 6.9

[Markus Julen]

Hi all!

Having just moved a small "outgoing only" mailserver to 6.9, I started to 
receive error messages:

> 80008bb60b9428ed smtp connected address=X.X.X.X host=z.z.z
> 80008bb60b9428ed smtp disconnected reason="io-error: handshake failed: 
> error:1402610B:SSL routines:ACCEPT_SR_CLNT_HELLO:wrong version number"

No filters, nothing, just plain smtpd. 6.8 worked flawlessly.

Has anyone managed to tweak the "cipher" option to the "listen" directive? Any 
other options to try?

Telling everyone to upgrade their mail client is probably no option as of now...

regards,

I use Zabbix with a "UserParameter"-bin to call "smtpctl show stats".

Re: question about CentOS 7 and OpenSMTPD-Extras

[Markus Julen]

Hi!

There's a very good step by step "recipe" at http://technoquarter.blogspot.ch, 
including ClamAV and spamassassin (and more). It's very easy to set up - even 
without filters.

Another very good guide can be found at 
https://frozen-geek.net/openbsd-email-server-1/

Virtual users, mysql? No problem.
