Bug description

I received an Axios error while setting up my email server, and no matter which email server I change, it always reports an error: AxiosError: Request failed with status code 400。

Regarding this error, I found a similar question to mine on the official forum of NextCloud, but the problem was solved by manually modifying the parameters of the smtp server in the configuration file. I tried the same method, but still received the error message "AxiosError: Request failed with status code 400".
It is worth mentioning that according to the documentation, I enabled debugging of email logs and adjusted the NextCloud log level to 0. When the request fails, I cannot receive any debug logs about emails.

Steps to reproduce

1. Open the basic settings
2. Device SMTP Mail Server
3. Error

Expected behavior

Can correctly set up the SMTP server

It should be noted that my Mariadb version is not recommended for V30.0.6. Is this related to it？

[bjo81]

I'm getting the same error on a freshly installed 30.0.6 (with MariaDB 10.11, so maybe that's not related). Unfortunately

"mail_smtpdebug" => true,
"loglevel" => 0,

logs nothing mail related and no SMTP -> get_lines() lines appear.

[dariocigna]

Same error here, and nothing found in log

I tried on different smtp accounts, same error

edit: only the test mail is not working.

other mail are correctly delivered

[bjo81]

As a workaround, set

('core','emailTestSuccessful','1',2,0)

in the oc_appsettings table of your Nextcloud database.

I'm having the same error with a fresh installation via docker and PostgreSQL. All mail, except the test mail, works as expected.
I checked my postgrestables (like @bjo81 suggested) and updated the values accordingly, since the entry existed already.

1. docker exec -it nextcloud-postgres psql -U nextcloud
2. SELECT * FROM oc_appconfig WHERE configkey = 'emailTestSuccessful';
3. UPDATE oc_appconfig SET configvalue = '1' WHERE configkey = 'emailTestSuccessful';

[Mazamazine]

Same error with a fresh install (30.0.6) on a VM on debian, using Sendmail or SMTP configurations (emails are correctly sent when creating an account tough, only the test fails). The debug mode didn't give any useful information. I only see the 400 in apache logs.

Changing the emailTestSuccessful doesn't work for me: as soon as I try testing the email configuration through the GUI, it's set back to 0. Unless I didn't understand the goal (at least the overview has no warning about this anymore). I also tried a different browser as suggested in another thread with no luck.

Yes, it will reset to 0 if you test again and it fails - but setting it to 1 removes the annoying message that you haven't configured e-mail.

I noticed that in this config port 25 is specified and not totally sure 163.com fully supports that anymore?

I have solved my question. If the problem occurs, you can try the following methods to solve it:

1. Manually configure the email server:

'mail_smtpmode' => 'smtp'，
'mail_sendmailmode' => 'smtp'，
'mail_smtphost' => 'smtp.mydomain.com'，
'mail_smtpauth' => 1，
'mail_smtpport' => '587'，
'mail_from_address' => 'noreply'，
'mail_domain' => 'mydomain.com'，
'mail_smtptimeout' => 30，
'mail_smtpname' => ' user@smtphost.com '，
'mail_smtppassword' => 'supersecretpassword'，

Note that it is necessary to add the configuration of 'mail_stmtptimeout'=>30.

2. At this point, if the newly created email server of NextCloud application still reports an Ajax error, the email transmission will fail. The reason is that the 'admin' account has not been configured with * * personal email * *. I speculate that the failure occurred because the personal email was not configured, and even if the email server was successfully configured, there was no target email address for testing.
   PS: I think this is a bug. The application should remind users that 'your personal email has not been configured yet' instead of causing us trouble. 'Why does it still report an error when I have configured the correct email address?'`
