This method is useful when sending short emails. As an example, lets send an email containing the message "'''Hello, JustTesting'''", from the hypothetical address '''[email protected]''' to '''[email protected]''' using Gmail's SMTP settings: | |||
echo -e "subject:Test\nfrom:[email protected]\nHello,\n\nJustTesting" | sendmail -v -H "exec openssl s_client -quiet -connect smtp.gmail.com:587 -tls1 -starttls smtp" -au"[email protected]" -ap"senders.email.password" [email protected] | :~# echo -e "subject:Test\nfrom:[email protected]\nHello,\n\nJustTesting" | sendmail -v -H "exec openssl s_client -quiet -connect smtp.gmail.com:587 -tls1 -starttls smtp" -f [email protected] au"[email protected]" -ap"senders.email.password" [email protected] | ||

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, lets 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>'''<mail.txt'''</span> -f [email protected] -au"senders.email@gmail.com" -ap"pass"[email protected] | |||
