problem with smtp gmail
After several tests, I find the following error:
530-5.7.0 Authentication Required. Learn more at 530 5.7.0 https://support.google.com/mail/?p=WantAuthError y18-20020a92d0d2000000b002f685e47b47sm428291ila.54 - gsmtp
After doing some research, I realized that Google has disabled the user and password authentication function for less secure applications, according to the following document: https://support.google.com/accounts/answer/6010255?authuser=7&hl=en&authuser=7&visit_id=637998656290115666-696177386&p=less-secure-apps&rd=1
in this regard, I'm not sure if it's possible to achieve this with password alone. You would have to modify the code to convert your application according to Google standards so that it can be authenticated.
in this sense, I don't think it's possible to continue using Gmail's SMTP for testing. I'm going to test SMTP from my own domain to test and see if I can manage to continue using your tool.
