Are e-mails to localhost logged with sSMTP?

I don't suppose that sSMTP will work for just sending mail on the localhost? nicholas@mordor:~$ nicholas@mordor:~$ sudo cat /etc/ssmtp/ssmtp.conf # # Config file for sSMTP sendmail # # The person who gets all mail for userids < 1000 # Make this empty to disable rewriting. root=postmaster # The place where the mail goes. The actual machine name is required no # MX records are consulted. Commonly mailhosts are named mail.domain.com mailhub=mail # Where will the mail seem to come from? #rewriteDomain= # The full hostname hostname=mordor.saundersconsulting.tech # Are users allowed to set their own From: address? # YES - Allow the user to specify their own From: address # NO - Use the system generated From: address #FromLineOverride=YES nicholas@mordor:~$ nicholas@mordor:~$ sudo cat /etc/ssmtp/revaliases # sSMTP aliases # # Format: local_account:outgoing_address:mailhub # # Example: root:your_login@your.domain:mailhub.your.domain[:port] # where [:port] is an optional port number that defaults to 25. nicholas@mordor:~$ nicholas@mordor:~$ swaks --to root@mordor.saundersconsulting.tech --from nicholas@mordor.saundersconsulting.tech --server mordor.saundersconsulting.tech === Trying mordor.saundersconsulting.tech:25... *** Error connecting to mordor.saundersconsulting.tech:25: *** IO::Socket::INET6: connect: Connection refused nicholas@mordor:~$ nicholas@mordor:~$ hostname mordor.saundersconsulting.tech nicholas@mordor:~$ nicholas@mordor:~$ lsb_release -a No LSB modules are available.
