So in short, the part beginning with '''echo''' and ending just before the column ('''|''') represents the email's header and body of text. Now lets examine the next part (the one that begins after the column):

So in short, the part beginning with '''echo''' and ending just before the column ('''|''') represents the email's header and body of text. Now lets examine the next part (the one that begins after the column):

'''sendmail <span style=color:green>-v -H</span> "<span style=color:blue>exec openssl s_client -quiet -connect smtp.gmail.com:587 -tls1 -starttls smtp</span>" <span style=color:red>-f [email protected]</span> <span style=color:purple>-au"[email protected]" -ap"senders.email.password"</span> <span style=color:brown>[email protected]</span>'''

'''sendmail <span style=color:green>-v -H</span> "<span style=color:blue>exec openssl s_client -quiet -connect smtp.gmail.com:587 -tls1 -starttls smtp</span>" <span style=color:red>-f [email protected]</span> <span style=color:purple>-au"[email protected]" -ap"senders.email.password"</span> <span style=color:brown> [email protected]</span>'''

* <span style=color:green>'''-v'''</span> - verbose mode

* <span style=color:green>'''-v'''</span> - verbose mode

This next method is superior when sending longer messages. Instead of using the echo command, we'll store our email header and body information into a text file. Just as in the example above, let's send an email from the hypothetical address '''[email protected]''' to '''[email protected]''' using Gmail's SMTP settings, but without using echo:

Just as in the example above, let's send an email from the hypothetical address '''[email protected]''' to '''[email protected]''' using Gmail's SMTP settings, but without using echo:

  :~# sendmail -v -H "exec openssl s_client -quiet -connect smtp.gmail.com:587 -tls1 -starttls smtp" <span style=color:red>'''</tmp/mail.txt'''</span> -f [email protected] -au"[email protected]" -ap"pass"[email protected]

  :~# sendmail -v -H "exec openssl s_client -quiet -connect smtp.gmail.com:587 -tls1 -starttls smtp" <span style=color:red>'''</tmp/mail.txt'''</span> -f [email protected] -au"[email protected]" -ap"pass" [email protected]

As you can see, instead of echo, we're using <span style=color:red>'''</tmp/mail.txt'''</span>, which is the path to the '''mail.txt''' file that stores the email's header and body. This file does not exist in the router, therefore, you should create it yourself. To create a file, use the '''touch''' command:
