GMail has disabled PLAIN authentication, encouraging use of their OAuth authentication method.
GMail has recently disabled AUTHENTICATE PLAIN support by default (while still advertising support on login), which can result in an exception with text such as 'No [WEBALERT *a long accounts.google.com address*] Web login required.' when attempting to log into your Gmail account (this will also generate an email sent to your Gmail account).
To enable AUTHENTICATE PLAIN under your Google account, navigate to your Google account's 'Connected Apps and Sites': https://myaccount.google.com/security#connectedapps and near the bottom of the page, enable the switch 'Allow less secure apps'.
PowerTCP Mail for .NET version 18.104.22.168, released April 7, 2016, adds OAuth 2.0 support, and the above is not necessary when using this authentication method. However it does require an application-level implementation of GMail's OAuth API. Its use with our component is covered here:
