I am in the midst of trying to get Kaltura to work on Ubuntu 10.4 but am experiencing an error that is a bit of a show stopper.
The good news is that I needed to configure Exim4 to send email via Gmail – and that is what this post is about.
First install Exim4:
sudo apt-get install exim4
Configure Exim with the following command:
sudo dpkg-reconfigure exim4-config
Press the down-arrow key to select mail sent by smarthost; received via SMTP or fetchmail then press Tab, followed by Enter:
Enter a system mail name – this might be your company-name.com or a dummy domain name like I used below:
Next we specify an IP address to listen for incoming SMTP connections. This field was already completed for me with the value 127.0.0.1 ; ::1
The next screen was auto-completed with my host-name (which I had previously edited in /etc/hosts). The guide that I followed said to leave this blank but I left it as it was:
I left the Machines to relay for blank:
Select No don’t Hide local mail name in outgoing mail:
Select No to Keep number of DNS-queries minimal (Dial on-Demand):
For Delivery method for local mail choose mbox format in /var/mail/:
For Split configuration into small files select No:
Now we need to make several changes to the configuration to Exim4 in the file etc/exim4/exim4.conf.template:
sudo nano etc/exim4/exim4.conf.template
Find the line .ifdef DCconfig_smarthost DCconfig_satellite and add the following in that section (you can press Ctrl + W to search in nano):
send_via_gmail:
driver = manualroute
domains = ! +local_domains
transport = gmail_smtp
route_list = * smtp.gmail.com
The guide that I followed said to remove any other smarthost defined with domains = ! +local_domains in /etc/exim4/exim4.conf.template but I did not find any.
Next find the comment begin authenticators section and add the following:
gmail_login:
driver = plaintext
public_name = LOGIN
client_send = : yourname@gmail.com : YourGmailPassword
Find the comment transport/30_exim4-config_remote_smtp_smarthost and add the following:
gmail_smtp:
driver = smtp
port = 587
hosts_require_auth = $host_address
hosts_require_tls = $host_address
Finally comment out the login section of /etc/exim4/exim4.conf.template:
#Commented out so that Gmail’s Public_name can equal “LOGIN”
#login:
# driver = plaintext
# public_name = LOGIN
#.ifndef AUTH_CLIENT_ALLOW_NOTLS_PASSWORDS
# Return empty string if not non-TLS AND looking up $host in passwd-file
# yields a non-empty string; fail otherwise.
# client_send = “<; ${if and{\
# {!eq{$tls_cipher}{}}\
# {!eq{PASSWDLINE}{}}\
# }\
# {}fail}\
# ; ${extract{1}{::}{PASSWDLINE}}\
# ; ${sg{PASSWDLINE}{\\N([^:]+:)(.*)\\N}{\\$2}}”
#.else
# Return empty string if looking up $host in passwd-file yields a
# non-empty string; fail otherwise.
# client_send = “<; ${if !eq{PASSWDLINE}{}\
# {}fail}\
# ; ${extract{1}{::}{PASSWDLINE}}\
# ; ${sg{PASSWDLINE}{\\N([^:]+:)(.*)\\N}{\\$2}}”
#.endif

Press Ctrl + O and then Enter to save and then Ctrl + X to save the file and exit nano.
Update Exim4 with the following command:
Run update-exim4.conf
Restart Exim4:
/etc/init.d/exim4 restart
Finally test your configuration by sending an email via the command line:
mail user@example.com
Type a Subject and then press Enter.
Type a message and then press Enter.
Type a single . (dot) and then press Enter.
Press Enter again for a blank CC address.
Within a few minutes you should receive an email at the specified email address.
