I used Outlook mailbox as SMTP.
When I register with the QQ mail box, I can activate it.
But other people feedback that they can't receive any email or activate it by using QQ mailbox. (I really can't get anything when I change a QQ mailbox.)
EMM so it's also a mystery.
If you want to know what mailbox you use for SMTP, will there be any restrictions?
Thank you very much.
