datdv1 created about a year ago

Hi Support Team ABP!

ABP Framework version: v7.4.2

UI Type:Angular

Database System: MongoDB

Tiered (for MVC) or Auth Server Separated (for Angular): yes

Currently, I'm setting email information in Emailing screen of angular side, I saved successfully,

After that, I click to button Send test email

and in the next step I input sender email address, target email address, Subject and body

and in the next step click o send

I got error: System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Authentication Required.

Can you help me for this issue? and suggest solution for this problem.
Thanks ABP Support Team!

It seems a generic SMTP error. Did you check:

Hi gterdem!
The sample that you give me can work normally.
However, I get the error when send working with email confirmation function

Let me explain about my feature:
When a user register to our system, an email confirmation will be automatically sent to that user. However, when send email confirmation, I get this error.

I think that the email function of confirmation email is having some issues
Please help me with this issue

Hello,

It seems to be related to (TLS) needs to be set to "Yes" in your SMTP settings. And you seem to enable the SSL already.

Is you SMTP server google? It may be related to

Captcha

2FA

Or different time-zone

as I've investigated from https://support.google.com/mail/thread/146949535?hl=en&msgid=147102610

I've limited knowledge on SMTP servers unfortunatelly. Can you check the items above to narrow down the diagnostics?
