 IO::Socket::INET6: connect: Network is unreachable
+Test was:  $ swaks -tls -f [email protected] -t [email protected] -s smtp.mail.yahoo.com:587 -a LOGIN
 Seemed to be an IPv6 problem.

+November 2015
+Gmail stopped working.  Try a PHP or Perl solution?  Does it require SSMTP or MSMTP?
+This did not work: https://productforums.google.com/forum/?hl=en#!topic/gmail/2tK2fR7yW-k;context-place=forum/gmail
+Directions [[http://mhawthorne.net/posts/postfix-configuring-gmail-as-relay.html|based on this page by Matthew Hawthorne]] worked: \\
+. Make a backup copy of /etc/postfix/main.cf
+. Edit /etc/postfix/main.cf to have these settings:
+<code>
+# sets gmail as relay
+relayhost = [smtp.gmail.com]:587
+#  use tls
+smtp_use_tls=yes
+# use sasl when authenticating to foreign SMTP servers
+smtp_sasl_auth_enable = yes
+# path to password map file
+smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
+# list of CAs to trust when verifying server certificate
+#smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
+# Below is provided by ca-certificates package (Mozilla CA root certificate bundle)
+smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt
+# eliminates default security options which are incompatible with Gmail
+smtp_sasl_security_options =
+# add debugging
+debug_peer_list=smtp.gmail.com
+debug_peer_level=3
+</code>
+. Add your own Gmail credentials to /etc/postfix/sasl_passwd \\
+<code>
+[smtp.gmail.com]:587  username:password
+</code>
+. Run the following as root: \\
+<code>
+# postmap /etc/postfix/sasl_passwd
+</code>
+. Make sure the /etc/sasl_passwd* files are owned by the postfix user: \\
+<code>
+# chown postfix sasl_passwd*
+</code>
+. Tighten permissions: \\
+<code>
+# chmod 600 sasl_passwd sasl_passwd.db
+</code>
+. Restart postfix: \\
+<code>
+# /etc/init.d/postfix reload
+</code>
+or
+<code>
+# service postfix restart
+</code>
+. Send a test message: \\
+<code>
+echo 'It works' | mailx -s 'Test message' [email protected]
+</code>
+. Check mutt configuration for proper "From" settings.
