When I moved my mail functionality (gmail) from my FreeBSD-server to Google Apps I was left with no way to send email from my server (sendmail disabled and gmail removed) from shell. I have no longer the need to recieve email from my server, thanks to Google! However, I needed to send emails from my server to report server status and report software/hardware errors.
This is how I solved the problem on my FreeBSD 7.0 server.
1. Freebsd has a guide for setting up send only with ssmtp. First you should install ssmtp.
cd /usr/ports/mail/ssmtp/ && make install clean
2. Then you need to configure ssmtp for Gmail. Create this file in /usr/local/etc/ssmtp/ssmtp.conf. Replace email and password with your Gmail-account settings.
root=youremail@gmail.com
mailhub=smtp.gmail.com:587
AuthUser=youremail@gmail.com
AuthPass=yourpassword
UseSTARTTLS=YES
3. Test ssmtp. First you have to create a textfile with the message that you are going to send. Copy the text between the lines below.
Save the text to ”testmessage.txt”.
————————–
To: youremail@gmail.com
From: youremail@gmail.com
Subject: Testmessage
This is a test
--------------------------
Then run this command to send the testmessage.
ssmtp -v youremail@gmail.com < testmessage.txt
You should see the following output:
[<-] 220 mx.google.com ESMTP 14sm2982172ewy.10

If everything seems ok you should now have a fresh email in your Gmail account. Check it out! If not, then you should probably check your ssmtp.conf file and verify that you can connect to smtp.google.com
4. Last, replace sendmail with ssmtp. This makes ssmtp the default mailer for your system.
mv /usr/sbin/sendmail /usr/sbin/sendmail.org
ln -s /usr/local/sbin/ssmtp /usr/sbin/sendmail
5. Check that mail is working.
mail -v -s "TestSubject" youremail@gmail.com

6. Check the log file.
cat /var/log/maillog
Output:

Summary
This worked for me straight out of the box. I didn't need to make any changes to make it work. I hope it works for you as well!
