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.

can be caused by file permission errors on
/etc/ssmtp/ssmtp.conf
. Whatever application is trying to runssmtp
cannot read the file.& add the application sending email to the
mail
group (e.glogcheck
if it is not part ofadm
group)For completeness your
smtp.conf
should look something like:sSMTP
uses256 bit
ciphers & verifies theCA
.
