I probably should have included a tail of my /var/log/maillog file:

  Jan 16 00:08:00 laptop sSMTP[6976]: Unable to connect to \
"mail.domain.org" port 25.
  Jan 16 00:08:00 laptop sSMTP[6976]: Cannot open mail.domain.org:25

As with the previous message, the server name and local hostname have been
sanitized thus:

"laptop" is the local machine using ssmtp
"domain" is the domain of the email address and SMTP server
