I've installed ssmtp and then edited the ssmtp.conf file so could try sending a mail but says cannot open mail:25 however in the conf file I set it to gmail port 467 and I am pretty sure everything else is right. What specifically do I need to look for with this error or could it be any number of settings in and outside of the configuration file?## /etc/ssmtp.conf -- a config file for sSMTP sendmail.## See the ssmtp.conf(5) man page for a more verbose explanation of the# available options.## The person who gets all mail for userids < 500# Make this empty to disable rewriting.root=postmaster# The place where the mail goes.
