Hi, Because of a new company policy need to switch our site email configurations from SMTP to oAuth. However, I can’t find that option in the admin panel. Any help? Thanks

SMTP sends emails (daily digests, password reset), while OAuth authenticates (and logs in) users. I don’t think they are substitutes for each other, unless I’m understanding wrong…

Hey @NateDhaliwal , hai qualche suggerimento su come poter procedere? Grazie

You’ll need to make a plugin or use a mail delivery service that uses smtp auth.

We switched to https://auth-email.com – it connects to the OAuth email service for you, so you can just use normal SMTP.

MailEnable ne prend pas en charge OAuth pour SMTP, contrairement à Microsoft et Google. Il utilise principalement l’authentification de base. Vous devrez probablement passer à un service SMTP externe comme Microsoft 365 ou Gmail, ou utiliser un relais qui prend en charge OAuth si votre politique l’exige.
