fujinuriman We tried adding webmail. However, the result is that email can only send messages and cannot receive messages. We have done the SSL settings (using SSL mail.domain.com), SPF, and DKIM. What's the best solution? Thank You.
aaPanel_Kern Hello, it is recommended to check whether the relevant domain name records are configured correctly? Check the log information of the mail server and see if there is any error log information? fujinuriman
