Problem Description
The problem lies in the password attribute of the target "send_emai". We think that the password entered is the email password. Even if the correct password is given and an error is still reported, we still ask everyone to enter the correct password. The results of it?
The "password" entered here is not a password, but an authorization code, which is a special password for logging in to third-party email clients. It is suitable for logging in to the following services: POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV services .
solution
After enabling the authorization code service in the email settings, change the password to the authorization code used, and the email is sent successfully.
