This is going to be a long, somewhat messy post.
Grant, I'll answer your questions where I have an answer, include the
requested files/data.
Post by Grant TaylorCan you confirm the port that Sendmail is connecting to?
Right host: Yes, remote IP address confirmed in tcpdump
Right port: Yes, port 587 confirmed in tcpdump
And reiterating from a previous post, using:
openssl s_client -starttls smtp -connect remote-server.com:587
z
I've verified that the remote server responds correctly, accepts AUTH
LOGIN and accepts & delivers mail subsequently.
Post by Grant TaylorCan we see the definition for the relay mailer?
Not sure what that means. "relay mailer" == "delivery agent" per
BatBook sec. 20.4?
Using mailertable. Converted to mailertable.db with "makemap hash..."
The sendmail.cf is relevant here so the corresponding sendmail.mc is
also included below. Have I screwed up here somehow by putting
"relay" in mailertable instead of "smtp"?

Because it's simple and short, I'm including my authinfo file here.
If, as it appears, the AUTH command is never sent to the remote
server, the authinfo presumably never gets used.
--- BEGIN authinfo ---
AuthInfo:remote-host.com "U:valid-username" "P:rEdAcTeD" "M:LOGIN"
--- END authinfo ---
Post by Grant TaylorCan you confirm that encryption is or is not being used?
It appears (see "sendmail -X log", below) that encryption *is*
started but then the AUTH command is never issued to the remote server
by my local sendmail. Do I have that right? I can post tcpdump of
the same session if it would reveal a vital clue.
Post by Grant TaylorCan we see (a redacted version of) the DSN?
See "sendmail -X log", below. What the "sendmail -X log" reports
seems to be a failure by my sendmail to issue the AUTH command once
TLS is running.
1. Transaction of handing mssg *to* sendmail on localhost.
Seems normal. No crypto or AUTH needed
2. Connect to remote server. My sendmail sends EHLO.
The remote server offers STARTTLS but *not* AUTH
3. My sendmail sends "STARTTLS"
Remote replies "Ready to start TLS" in plaintext
This point can be identified in the tcpdump log.
4. My sendmail sends *another* EHLO
Now the remote replies, offering AUTH PLAIN LOGIN
This is *not visible* in the tcpdump -X output as plaintext, so
I infer that TLS is in effect.
5. My sendmail does *not* issue the AUTH command.
Instead, it immediately proceeds to MAIL FROM:
The remote server rejects the mssg.
Here's the session log recorded by adding "-X filename" to
rc.sendmail, the script that runs/restarts sendmail.
It appears to include transcripts of:
+ Receiving mssg from my email client
+ Connecting to remote server and attempting to send mssg
+ Reporting failure to root on local host. A mail mssg to root
showed up in /var/spool/mail/root with substantially the same
text as in the session transcript next below.
Following log is redacted: "valid-***@remote-host.com" always
represents the same ***@address. "smtp.remote-server.com" replaces
the server name I use as well as the CNAME of the same host where it
responds with it.
