Ubuntu 20.04 sending email from AWS

[Jerry Geis]

Hi - trying to send email (sendmail) on port 587 from AWS image.

When I use telnet it connects - so 587 is a valid path...
telnet smtp-relay.gmail.com 587
Trying 142.250.112.28...
Connected to smtp-relay.gmail.com.
Escape character is '^]'.
220 smtp-relay.gmail.com ESMTP
l15-20020a17090a150f00b001dfac278995sm682651pja.12 - gsmtp
^]quit

When I run interactive session:
sendmail -Am -v -t
To: X at Y
From: X at Y
Subject: test

X at Y... Connecting to aspmx.l.google.com. port 587 via esmtp...

sendmail.mc has
define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
define(`RELAY_MAILER', `esmtp')dnl
define(`null_client', `smtp-relay.gmail.com.')

I dont understand why 587 is not connecting. It connects on the manual
telnet.
It does not connect otherwise.

What might I be missing?

Jerry
