problem description
Flask Web development chapter 7, after adjusting the project structure, found that new users will not send mail, there is no error prompt (chapter 6 debugging is able to send mail). I have checked junk mailboxes that are not in my inbox and there is no bounce behavior
the environmental background of the problems and what methods you have tried
Baidu hasn"t found a good solution for a long time. The console has the following error, but it feels irrelevant:
DVV pythonlibsitelypackagespymysqlcursors.pyrang170: Warning: (1366, "Incorrect string value:"\ xD6\ xD0\ xB9\ xFA\ xB1\ xEA." for column "VARIABLE_VALUE" at row 48

what result do you expect? What is the error message actually seen?
after the program runs, enter the user name, there is no error, but also did not receive the new user to join the e-mail, how to receive the e-mail. I can"t see what went wrong
