I'm trying to rebuild a server after an upgrade. The mail server did not work
after restoring backup configs, so I have been trying to rebuild it. In the
process I'm moving from cyrus to dovecot. That seems okay, but I'm having real
trouble getting things to happen here. Note that this mail server is here to
move mail on the LAN only, there is no access to anything outside this LAN
required.
I can telnet into all the relevant ports okay. I can openssl into the secured
ports from the server as well as a client machine. Trouble is, I can't actually
send mail from any machine. The user madams is the ID for root in postfix (from
postfix/aliases: root: madams), all other aliases are for root and these are
the only 2 users on the system at this point. I have run newaliases with no
error.
Here is how a transaction goes under telnet:
$ telnet shuttle 25

Cyrus-imapd is disabled and not running, but I'm not seeing any errors. In
fact I'm not seeing any errors anywhere. I see no errors when manually starting
postfix. I see no errors in journalctl or in /var/log/mail/errors.log or
/var/log/mail/warnings.log. As should be seen above, I have postfix configured
for verbose logging (smtp -v) but I'm not getting anything.
Here is the startup for postfix from jounralctl -xe:

Can anyone see what I'm missing?
Thanks in advance.
