Qmail and outgoing SMTP
Posted: Sun Oct 25, 2020 4:47 pm
I have problems with Qmail and outgoing SMTP mail. With few domains Qmail cannot get a TLS negotiation. I wanted to switch off TLS for those domains and did so by putting those domain*s FQDN as files unter the directory var/qmail/control/notlshosts .
But this does not work (new SMTP connections still use TLS) and even if I stop the Qmail SMTP daemon, I can still reach SMTP on my server. So I assume that MagicSpam includes an own SMTP server which might interfere with the special functions of the original Qmail SMTP server.
Is this true and is there any way to instruct the outermost SMTP server to build up an unencrypted connection to certain domains.
Another idea would be to exclude certain encryption types like SSLv3.
