I had another toaster user do the following
# cd /var/qmail/control
# cp -p tlsserverciphers tlsserverciphers.bak
# echo
'TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256:TLS_AES_128_CCM_SHA256:DEFAULT@SECLEVEL=1:HIGH:!DH:!aNULL'
> tlsserverciphers
# qmailctl stop
# qmailctl start
Mail delivered properly.
It might be worth a try to change SECLEVEL=1 to SECLEVEL=2 for greater
security:
# echo
'TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256:TLS_AES_128_CCM_SHA256:DEFAULT@SECLEVEL=2:HIGH:!DH:!aNULL'
> tlsserverciphers

In my case the cause was that I removed some DH (Diffy Hellman)
cyphers, probably to much to be good ;-)
Restore to the old cypher config fixed the error:
TLS connect failed: error:0A00018A:SSL routines::dh key too small;
connected to xx.yy.zz.213.

Can you expand on what that means, and how you fixed it?
Thanks!

Hello guys any suggestions on this?
deferral:

Thanks,
I generated a new key of 4096 but still got this error.
