Hello,
I have a question or a problem of understanding.
When I try to connect through the the command line utility openssl to
port smtp or submission I get this output:
$ openssl s_client -connect odin42:25
CONNECTED(00000003)
139782539474752:error:1408F10B:SSL routines:ssl3_get_record:wrong

And in /var/log/maillog on the server these messages appears:
Jan 19 19:41:07 odin42 smtpd[25442]: 430c551fc99f310d smtp connected

address=194.96.2.67 host=194-96-2-67.adsl.highway.telekom.at reason=quit
When I connect to smtps port, everything works fine.
Here is my listen setup of OpenSMTPD:
# listen setup
listen on lo0
listen on lo0 port 10028 tag DKIM
listen on egress tls pki mx1.krottmayer.com.pki auth-optional
listen on egress smtps pki mx1.krottmayer.com.pki auth
listen on egress port submission tls pki mx1.krottmayer.com.pki auth
Could somebody check my configuration, please?
Thanks in advance!
