I have the following ssmtp.conf file:

[email protected] mailhub=smtp.gmail.com:587 hostname=ed424cef9b52 UseTLS=Yes UseStartTTLS=Yes AuthMethod=LOGIN AuthUser=test AuthPass=test FromLineOverride=yes TLS_CA_File=/etc/ssl/certs/ca-certificates.crt

I can connect to 587 gmail port:

telnet smtp.gmail.com 587 Trying 64.233.186.109... Connected to gmail-smtp-msa.l.google.com.

But when I try to send mail:

/usr/sbin/ssmtp -v [email protected] < qq ssmtp: Cannot open smtp.gmail.com:587 echo test | mailx -s "testing ssmtp setup" [email protected] send-mail: Cannot open smtp.gmail.com:587 Can't send mail: sendmail process failed with error code 1

The proper port is 465

Simplest way to send mail with image attachment from command line using gmail?

EXCERPT:

Install ssmtp with the following commands:

sudo apt-get update sudo apt-get install ssmtp

Then go into /etc/ssmtp and edit ssmtp.conf to look like this:

[email protected] mailhub=smtp.gmail.com:465 FromLineOverride=YES [email protected] AuthPass=testing123 UseTLS=YES

Send a one-liner like so:

echo "Testing...1...2...3" | ssmtp [email protected]

Send a formatted text file like so:

cat mymessage | ssmtp [email protected]

Where mymessage can be formatted to have lines for TO: and SUBJECT: and the body.

TO: [email protected] SUBJECT: Testing -blank line- Message body goes here....
