ssmtp: Cannot open mail:25

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. The actual machine name is required # no MX records are consulted. Commonly mailhosts are named mail.domain.com # The example will fit if you are in domain.com and your mailhub is so named. mailhub=mail # Example for SMTP port number 2525 mailhub=smtp.gmail.com:465 # Example for SMTP port number 25 (Standard/RFC) # mailhub=mail.your.domain # Example for SSL encrypted connection # mailhub=mail.your.domain:465 # Where will the mail seem to come from? #RewriteDomain= # The full hostname #Hostname= # Set this to never rewrite the "From:" line (unless not given) and to # use that address in the "from line" of the envelope. #FromLineOverride=YES # Use SSL/TLS to send secure messages to server. UseTLS=YES UseSTARTTLS=YES AuthUser=user@gmail.com AuthPass=xxxxxx # Use SSL/TLS certificate to authenticate against smtp host. #UseTLSCert=YES # Use this RSA certificate. #TLSCert=/etc/pki/tls/private/ssmtp.pem TLS_CA_File=/etc/pki/tls/certs/ca-bundle.crt # Get enhanced (*really* enhanced) debugging information in the logs # If you want to have debugging of the config file parsing, move this option # to the top of the config file and uncomment #Debug=YES Interestingly all the files in /etc/pki/tls/certs/ are the exact same ones I deleted in my /etc/ssl folder! haha Now I know a certain amount of business happened when creating an untrusted cert.
