Steps To Reproduce

Go to login page and Input password
Click on 'login'
error

Expected Result

I declare in advance that I used the beta version of the code to test whether it was a real issue, and this is also the issue in the official version.

I have configured the SMTP server (QQ email) on the admin page
Click on test, an error message appears as shown below, but the test email received the email
Change the SMTP service provider, email sending is normal, and the software is working properly.
There was no problem in using it before. So I initially think that the qq mailbox may have made some changes to the return value or other aspects, resulting in an abnormality in the code?

Actual Result

like Expected Result

Enable SMTP_DEBUG=true and see what it reports. I do not think we can change anything to solve this.

thank you answer,this is my log with SMTP_DEBUG=true. I hidden my email address.

Looking at it again, i see the following

Internet access: false
Which means there is no internet access, not sure how your instance is able to send out an email at all this way.
It might also be something which is between you and the mail server which is causing an issue.

Do you maybe have changed the email templates?

Sorry bro，I don't know why it shows no network，but it does have a network.
As I said, although it reported an error when I used the QQ mailbox, my destination mailbox did receive the relevant email. When I switch to another mailbox service（such as @163.com mailbox）, there is no error. Everything is fine.

Enable SMTP_DEBUG=true and see what it reports.
I do not think we can change anything to solve this.

@LTI-Lennox A touch of the same, me too. A temporary solution:

enter the admin background, in the "SMTP Email Settings" will be closed smtp
If you can't log in to your bitwarden account, you can also disable 2FA for the corresponding account in "Users" on the admin page.
Before the above operation, please remember to backup your password data!

@BlackDex commented on GitHub:

I Would say to report this to qq actually. This seems an issue with the implementation of there SMTP server.
It's a bad idea to add exceptions for specific errors like this into our code.

You could try to add a custom mail-proxy in between maybe? But good chance it also might generate errors.
Since this is really something coming from the remote mail server, and not something which is a specific bug on the Vaultwarden side, I'm going to move this to a discussion.
