Is it aem cloud service or ams/on-prem? In aem cloud service you need to configure proxy port but in ams/on-prem it should be straight forward.

Its AMS

For gmail-smtp ,you need to use app password, for that two step authentication should be already enabled. Create app password using the link -    https://myaccount.google.com/apppasswords

I created the app password but still got the same issue

Hi @aem_noob,

Looks like authentication problem for Port 465 with Gmail.

For Yahoo, The 550 Response code could be because of any of the reasons listed in the How to Fix Yahoo Mail Error 550 Mailbox Unavailable

Can you try using a different SMTP provider? (Send Grid, Brevo, Mail Trap etc.)

I used Brevo for my local development and it works perfectly fine- 

Hope this helps!

Its working with 3rd party SMTPs yes
But why would they not work with Gmail and Yahoo any pointers?
