[42] How to configure RT5 & E-mail.

—Guide Start Here–

Configure mail account

Navigate to Outlook.com and login or create a new account.

Once logged in, enable the account to use POP.

Settings -> Email -> Sync email. Set “Let devices and apps use POP” to yes.

You will also need to provision an Application Password.

Select My Account

Then Security -> Update

Advanced security options -> Get Started

App passwords -> Create a new app password

Copy your app password that was generated we will use this later in postfix and fetchmail

Install and configure Postfix

Now that the Outlook.com portion is sorted lets login to our RT5 server

ssh to your RT server

ssh hendgrow@

Install Postfix

sudo apt-get install postfix

Select “Internet with smarthost”

Enter the SMTP server for Outlook.com = smtp.office365.com

We now need to edit a few things for Postfix to work as expected by editing the main.cf file and add the below

Our config used during this how-to can be found here – > HendGrow_Sample_Main.cf

sudo vi /etc/postfix/main.cf

smtp_sasl_password_maps = static:hendgrow@outlook.com:pbjxdgxauybypskz

smtp_sasl_auth_enable = yes

smtp_tls_security_level = may

smtp_sasl_security_options = noanonymous

relayhost = [smtp.office365.com]:587

Restart Postfix for the changes to take

sudo service postfix restart

RT user creation and assign mail address.

Login to RT and Create a new user for use with this email address. We will create user HendGrow that will be used to respond to support requests.

Login to your RT instance and create the support user /user as shown below

Admin -> Users -> Create

Under “E-Mail” capture the email address you wish to use. in our case it is hendgrow@outlook.com

Grant permissions to General queue for the new support user.

Admin -> Queues-> Select

Select the General queue

Select User Rights

Select the user and assign the required permissions.

Apply changes by clicking Save Changes

Testing outgoing mail

login as the support user you created in the previous step. Send a test mail to confirm postfix is working with office365.com by creating a new ticket.

On the RT server check the /var/log/mail.log log file for any issues. You should get a response as below. we looking for the status=sent

tail -20f /var/log/mail.log

Installing and configuring Fetchmail

To enable RT to fetch mail from our mailbox and generate tickets we need to install fetchmail.

ssh to your RT server

ssh hendgrow@

Install Fetchmail

sudo apt-get install fetchmail

Ensure that fetchamail is not running and create the fethcmailrc file.

sudo service fetchmail stop

sudo vi /etc/fetchmailrc

Our config used during this how-to can be found here – > fetchmailrc

Navigate back to RT and set create permissions for “Everyone” on the General Queue.

Admin -> Queues -> Select

Select General

Grant Everyone “Create Tickets” rights.

Testing incoming mail and ticket generation.

Send an email to the mailbox so fetchmail has content it can fetch. (We sent a mail from support@hendgrow.com to our mailbox hendgrow@outlook.com)

Set permissions and run fetchmail manually for the test.

sudo chmod 0700 /etc/fetchmailrc 

sudo fetchmail -f /etc/fetchmailrc

Login to RT and verify a new ticket has been created for the incoming email.

Edit the crontab to ensure fetchmail checks for new mail in the mailbox every 5min.

sudo crontab -e

Add the following line

*/5 * * * * fetchmail  -f /etc/fetchmailrc

Your RT5 ticket system should now have the capability of sending and receiving emails for ticket creation and correspondence.
