In a later version of redmine, there is no email. yml and it is merged with configuration. yml. You only need to configure configuration. yml.
First, let's talk about the redmine mail. to configure this mail, you can send emails to developers and testers through your set email account (username) and password. If you configure a 163 mailbox, you can send it to them through the 163 mailbox. Developers and testers do not have to worry about what their mailboxes are, as long as their mailboxes are correct. (If the email is successfully sent, you can view the email you set and click "sent" to see the email you have sent)
So the username and password are correct.
Default:
# Outgoing emails configuration (see examples abve)
Email_delivery:
Delivery_method: SMTP
Smtp_settings:
Address: smtp.qq.com
Port: 25
Domain: QQ.com
Authentication: Login
User_name: "email account"
Password: "email password"
During configuration, the email address and domain are configured with the account you wrote in your username as a domain name. For example, your username is [email protected]. The password is your 163 mailbox password, and the address is smtp.163.com domain is 163.com. if it is [email protected], then the password is your QQ mailbox password, and the address is smtp.163.com domain is 163.com
Note: there is a space after the colon. If there are two colons, no space is required.
