Mail notification doesn´t work anymore after update from 27.0 to 27.1

Hi,

After th update from NC 27.0 to NC 27.1, the email notification no longer works. I always just get the error message “A problem occurred while sending the email. Please revise your settings” . I tested all settings in both, the GUI and config.php and still got the same Error message. Here are my settings in config.php:

‘mail_from_address’ => ‘a.xxxx’,
‘mail_smtpmode’ => ‘smtp’,
‘mail_sendmailmode’ => ‘smtp’,
‘mail_domain’ => ‘xxxx.at’,
‘mail_smtphost’ => ‘mail.xxxxx.at’,
‘mail_smtpport’ => ‘587’,
‘mail_smtpauthtype’ => ‘PLAIN’,
‘app_install_overwrite’ =>
array (
0 => ‘backup’,
),
‘updater.secret’ => ‘dsfgfgergbdfhgfdhthrerthrthrtgnhrthnrthr’,
‘mail_smtpauth’ => 1,
‘mail_smtpsecure’ => ‘tls’,
‘mail_smtpname’ => ‘a.xxxx@xxxx.at’,
‘mail_smtppassword’ => ‘xxxxxx’,
);

Email server

It is important to set up this server to be able to send emails, like for password reset and notifications.

Send mode SMTP
Encryption None/STARTTLS

From address a.xxxx@xxxxx.at

Server address mail.xxxxx.at:587

Authentication x

Credentials a.xxxx@xxxx.at xxxxx

Test and verify email settings
A problem occurred while sending the email. Please revise your settings. (Error: Email could not be sent. Check your mail server log)

Anyone an idea? Would save my day. Tank you

Please take a look at https://github.com/nextcloud/server/issues/40073 and the related issues on GitHub.

Hi kesselb,

thank you for your reply and your tip. The error was due to an expired certificate on my mail server. It works again since yesterday!
