What doesn't work? Can't send mail.
Long before Verizon and Oath were involved with Yahoo.

When I switched from dialup AT&T had me using port 465 and at that
time I was getting some kind of authorization error but couldn't find
out what.

# /etc/exim4/update-exim4.conf.conf

Here's an excerpt from current exim's log:
2018-07-03 19:51:29 1faXd0-0008Gb-JB Remote host
smtp.att.mail.fy4.b.yahoo.com [] closed
connection in response to initial connection
2018-07-03 19:51:59 1faXd0-0008Gb-JB == nialccm.ekim@xxxxxxxxx
R=smarthost T=remote_smtp_smarthost defer (-18): Remote host
smtp.att.mail.fy4.b.yahoo.com [] closed connection in
response to initial connection

Switching update-exim4.conf.conf to read:

exim's log now shows:
2018-07-03 20:15:24 1faYFl-00006U-4d ** mikemcclain.46@xxxxxxx
R=smarthost T=remote_smtp_smarthost: SMTP error from remote mail
server after MAIL FROM:<> SIZE=2464: host
smtp.att.mail.fy4.b.yahoo.com []: 550 Request failed;
Mailbox unavailable

This last message shows a further complication. I have a primary email
account with ATT as well as several aliases,. I also have a Yahoo
account, likewise gmail and am likely to use any of them as the source
(From:, ReplyTo: headers) in outgoing mail depending on where it's going.
I only have one, the primary, in /etc/exim4/passwd.client for ATT.

My dialup doesn't care what I call myself when I send email but
perhaps ATT/Yahoo does.

No I haven't tried to get that special password.

What I've got works, I guess I'll leave it rather than jump through
hoops for Verizon.

Thanks for the references.
