Problem

How do I set up outbound SMTP in WHMCS?

Solution

This article details how to modify the Mail Settings inside WHMCS to send emails outbound via a SMTP service using outMail.  outMail is a cloud based outgoing SMTP service.

The following example assumes you have already got a fully functional WHMCS eCommerce solution installed.

Log into your WHMCS Admin area. 

Under the Setup Menu select "General Settings"

WHMCS Setup & General Settings Menu

 

Now select the "Mail" tab.

Change the "Mail Type" to SMTP.

Then enter the outMail settings you were provided with.


WHMCS Email Settings

 

  • Mail Type = SMTP
  • SMTP Port = 25 (or 587, 2525 or 8025)
  • SMTP Host = <outMail server provided in the welcome email>
  • SMTP Username = <outMail username provided in the welcome email>
  • SMTP Password = <outMail password provided in the welcome email>
  • SMTP SSL Type = None (see notes below on other options)

  • Click "Save"

Using SSL or TLS

First get the connector running with the Protocol set to none.

Once you're happy its working you can enable SSL or TLS encryption options by changing the "SMTP SSL Type" field.

For SSL, remember you will need to change the port to 465.

For TSL, all ports are supported.

Note on SPF

If your domain name has already implemented SPF (Sender Policy Framework) records, then please ensure you update that record to include the SPF records for outMail.
