GMail has strict rules for accessing emails by less secure applications. In order to allow GMail account to be accessed by less secure applications, you should enable the access by configuring your email account. https://support.google.com/a/answer/6260879?hl=en

Please try it at your end and if the issue still persists, you can write to us on Aspose.Email forum for further assistance.
