Configure an Outgoing Mailbox

To send email notifications to your users, you need to define an outgoing mailbox. This guide explains the procedure for setting one up.

Configuration Steps

In the Deepser Backend, navigate to System > Tools > Email > Mailbox.
The grid shows already configured mailboxes. Click the + Add Mailbox button in the top right corner.
Set the mailbox type to OUT. All relevant fields will load dynamically.

Tab	Field	Description
General Data	Name	Descriptive name used in the system.
	Type	IN (to receive) or OUT (to send emails).
	Status	If "Disabled", email integrations are not active.
	Email Display	The displayed email address. Not the username -- use this if your server allows a different address for outgoing messages.
	Display Name	Name shown in the "From" field (e.g., "Your Service Desk").
	Host	Address of the mail server.
	Port	Port for the connection.
	Encryption	Encryption type for the connection.
	User Name	Username (usually the email address) to connect.
	Password	Password to connect.
	Protocol	Protocol to send emails (SMTP or OWA).
	OAuth Client	OAuth2 client used for authentication on services that require it.
System Data	Prefix	Prefix prepended to the record ID in the email subject. Used by the incoming mailbox to match replies to existing records. For example, with prefix "TICKET#", emails are sent with subject "TICKET#70".
	Allowed Emails	Whether emails can be sent only to registered users or to any address.
	Is Default Outgoing	Indicates whether this is the default outgoing mailbox. Every Service Operation has a Mailbox ID field; if not set, the default mailbox is used for notifications.
	Exclude Expression	A regular expression to block emails whose recipients match the expression.
Advanced	Custom Code	PHP code executed after an email has been sent, for triggering custom events.

After saving, click the Check button (top right) to test the connection.

If configured correctly, a success message will appear. Otherwise, an error message will be displayed.
