Hi John,

    There is no vulnerability. Its Gmail trying to sell its two factor authentication as well as SPF, DMARC and DKIM . Almost no-one has implemented all these protocols and any, if not all users have experienced disabling problems. The solution is to turn off this new setup and go back to the previous standard international protocols.

The only problem I have with pmail is that the pop implementation in 4.73 has some security vulnerability, would be great if this could be fixed.  Thanks

Have you got any article that describes the vulnerability and any fixes announced?

We have no vulnerability article so cannot proceed to investigate or possibly fix this "problem". Please provide us with the article you are citing

Sorry about the lack of info.  I tried to set up Pop in Gmail.  Didn't work and when I went to help it said "If an app or device doesn’t meet our security standards, Google will block..." and suggested I could turn on "less secure access".  I did that and the Pop then worked, so I assumed that there was a vulnerability.
