These are instructions on how to enable SMTP Authentication on common email programs. SMTP Authentication must be enabled on your email program / application in order to send outgoing email. This is a requirement on most mail servers.
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. Most webmail programs have SMTP Authentication enabled by default, but many desktop email programs (like Outlook, Thunderbird, Apple Mail etc.) will disable it by default. It’s important to check if SMTP Authentication is required for every email account used or you could 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.
