python - flask_mail, mails are stuck on thread and are never send -

i'm using flask + socketio ssl, , i'm trying send mail, reason, sending mail not working.

here configuration:

app.config['mail_server']='smtp.gmail.com' app.config['mail_port'] = 465 app.config['mail_username'] = 'xxx@gmail.com' app.config['mail_password'] = 'xxx;' app.config['mail_use_tls'] = false app.config['mail_use_ssl'] = true app.config['debug'] = true  mail=mail(app) 

...

and when i'm using it:

@app.route('/testmail') def testmail():     msg = message(               'hello',            sender='xxx@gmail.com',            recipients=['xxx@gmail.com'])     msg.body = "this email body"     mail.send(msg)      return "" 

and here error log:

for reasons, can't send email. seems stuck because of socketio + ssl wrapping. i've got no idea on how configure right way

i had same issue, if working in virtual machine check network connection ssh port, in case work vagrant, enabled connection ssh port, code works me:

from flask import flask flask_mail import mail, message  # object flask , object mail  app = flask(__name__) #configuration flask mail app.config.update(              mail_server = "smtp.gmail.com",              mail_port = 465,              mail_username = 'xxx@gmail.com',  #user mail              mail_password = 'xxx',              mail_use_tls = false,              mail_use_ssl = true,              mail_default_sender  =  'xxx@gmail.com', #user go email) mail = mail(app)  @app.route("/index") def index():     return "ok"   @app.route("/test mail") def test_mail():     """route test email flask mail."""     msj = "this test send mail flask."     recipients = ["xxxemail@gmail.com"]     msg_object = message("hello", recipients)     msg_object.body = "hello, email test"     mail.send(msg_object)     return "sent"    if __name__ == '__main__':     app.run(host="0.0.0.0", port=7000, debug=true) 

also, should verify if built-insecurity features in gmail service may block login attempt. log in account , visit https://www.google.com/settings/security/lesssecureapps.
