# Alternative Email Configuration Methods¶

There are several methods of configuring Liferay DXP to connect to a mail server. The simplest way to get started is to configure mail using through the Server Administration UI. This article covers alternative methods for configuring mail; Using Portal Properties or using an application server’s mail session.

## Configuring the Built-in Mail Session Using Portal Properties¶

To configure the mail session offline or before deploying DXP:

1. Create a portal-ext.properties file (if the file does not already exist).

2. Copy these default property settings into the portal-ext.properties file:

mail.session.mail=false
mail.session.mail.pop3.host=pop.gmail.com
mail.session.mail.pop3.port=110
mail.session.mail.pop3.user=joe.bloggs
mail.session.mail.smtp.auth=true
mail.session.mail.smtp.host=smtp.gmail.com
mail.session.mail.smtp.port=465
mail.session.mail.smtp.user=joe.bloggs
mail.session.mail.store.protocol=pop3
mail.session.mail.transport.protocol=smtp

3. Replace the default mail session values with your own.

4. Put the portal-ext.properties file into the Liferay Home.

DXP connects to the mail session on the next startup.

## Connecting to a Mail Session on the Application Server¶

Users can opt to configure a mail session for DXP using their application server.

1. Create a mail session on your application server; please see the application server’s documentation.

2. If using the Control Panel, navigate to Control Panel → Configuration → Server Administration → Mail.

3. Enter the value in the JavaMail Properties field.

4. Click Save. This points DXP to the mail session on your application server.

The mail server has been connected to DXP and ready to send notifications.

Note

Setting the following property in portal-ext.properties and restarting your server will have the same effect as setting the value in the Control Panel: mail.session.jndi.name=mail/MailSession
