Stop merging unrelated bug reports and instead fix the bugs!
Twice I have reported the same bug and you've merged my feedback with an unrelated issue rather than responding. Here's the issue:
In Account Security settings, when Allow apps that use less secure sign in is off, your pop server no longer responds to pop clients, even when Two step verification is off. This has to be wrong. pop is no less secure than browser access.
Another bug you haven't fixed but merged with unrelated issues:
It is impossible to keep messages from being sent to the Spam folder.
In case your email client uses basic authentication, you will need to enable the ‘Allow apps that use less secure sign in’ option in order to connect to the POP/IMAP or SMTP servers.
If you find that an important email was sent to the Spam folder, mark the email as “Not Spam” (as opposed to manually moving it to the Inbox), that way you will train the spam filter to better identify important emails in the future.
