You can use your own email server to send replies on tickets. This can configured under the category's settings.

The steps to do this are as outlined below:

Step 1: Navigate to Manage >> Categories and click edit next to the category you're looking to configure the SMTP for.

Step 2: Scroll down to Outgoing Mail Options, click show advanced options, and accept any pop-ups or prompts that appear.

Step 3: Select "Use Own SMTP" from the drop down menu under SMTP Account.

Step 4: Enter your SMTP account's hostname details and credentials in the respective fields.

Step 5: Click "Test Connection" to verify if the credentials you entered are all correct, and to confirm if the SMTP server connection works.

Step 6: Add the spf record "include:spf.happyfox.com" to your DNS. We strongly recomment to set the SPF record to ensure all the replies sent from HappyFox are delivered to your customers. 

Step 7: Once you have added the SPF record, you can verify the status in HappyFox using "Re-verify" option.
