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…

If I understand correctly, I think a similar question has been asked a few years back, and this was the response: [image] Basic Auth Disabled in Office 365 Self-hosting Looks like there’s no need to switch to OAuth2. SMTP AUTH will still be available when Basic authentication is permanently disabled on October 1, 2022. So, you should be able to change to SMTP Auth by adding an additional env variable to app.yml. DISCOURSE_SMTP_AUTHENTICATION: cram_md5 In addition to that I think you will need to use the MD5 hash of the SMTP password as value of the DISCOURSE_SMTP_PASSWORD setting. Rebuild the Docker container after those changes and give it a try.

Grazie per la referenza alla discussione precedente. Tuttavia da parte del nostro IT mi dicono: This response seems to be misleading. SMTP Auth is a parent category that includes both basic and modern auth (OAuth2). By the description of the configuration, you are still configuring basic username and password. Here is an explanation from the Microsoft forums: “SMTP AUTH is usually recommended by most vendors/suppliers and is supported by most apps/devices. SMTP AUTH can be done using Basic and Modern Auth, depending on the vendor/app/device (but since MS is deprecating basic auth, it needs to be configured with Modern Auth)… Modern authentication is based on the Active Directory Authentication Library (ADAL) and OAuth 2.0.” https://learn.microsoft.com/en-us/answers/questions/1141052/definitive-guide-to-smtp-auth-vs-basic-auth-vs-oat So while it is correct that Microsoft is not discontinuing SMTP Auth, it is true that one of the methods included in SMTP Auth will not be available (specifically using a username and password). La soluzione suggerita non sembra applicable per come viene descritta. Come possiamo fare?

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.

Chi potrebbe aiutare nella creazione del plugin? Oppure conosci qualche servizio che utilizza l’autenticazione SMTP? Grazie

[image] Pierpinna: Who could help with the creation of the plugin? You can post a topic on #marketplace, and hopefully hire a developer, for a fee.

[image] Pierpinna: do you know any service that uses SMTP authentication? Virtually all mail services use SMTP authentication. All of those mentioned in Configure VERP to handle bouncing e-mails, for example.

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