How to enable SMTP Authentication if you cannot send emails

These are instructions on how to enable SMTP Authentication on common email programs. SMTP Authentication must be enabled on your email program in order to send outgoing email. This has been a requirement on all Maxer Host mail servers for many years.

SMTP Authentication simply means your email program is providing your full email address and password when you send outgoing emails to prove who you are. Our webmail program has SMTP Authentication enabled by default, but many desktop email programs (like Outlook, Thunderbird, Apple Mail etc.) will disable it by default. It’s important that SMTP Authentication is enabled for every email account provided by Maxer Host or you will encounter error messages or bounce-backs with your outgoing emails. It only takes a minute to check if it’s enabled.

Please note that if you do not have SMTP Authentication enabled, this will decrease the “reputation” of your email address, and other email providers like Yahoo, Hotmail and Google Mail will be more likely to mistake your incoming emails for spam.
Please follow the relevant instructions below to verify SMTP Authentication is enabled.

Microsoft Outlook 2016, 2019, 365 and newer

4. Click on the "Repair" button
