Enabling SMTP Authentication

SMTP stands for Simple Mail Transfer Protocol. It helps with the authentication when sending email because it identifies the origin of the email sender which therefore stops emails being sent anonymously, therefore helping to combat spam. It is always recommended to enable SMTP authentication (where available). All of our help articles in the '[Email Setup](https://hostpresto.com/help/category/2/)' section include enabling SMTP authentication, however, you can check that you have this option enabled on your system by following the following guide for your respective email client. --- ### Microsoft Outlook Open Microsoft Outlook.
