I am trying to send e-mail through the POP3/SMTP VBO, using the G-Mail SMTP server (requirement for this project).
Unfortunately, so far I am having no luck getting this to work.
I consistently get the following error: "The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required."
I am using the SMTP settings as recommended on Google's SMTP settings help page:
https://support.google.com/a/answer/176600?hl=en
I have tried all possible permutations of SMTP ports and enabling/disabling SSL in the VBO's "Configure" action and I am providing the G-Mail credentials I was provided for the project.
I have taken the necessary steps as far as I know, for instance enabling the "Allow less secure apps" setting in Gmail, but to no avail.
Does anybody have any experience automating G-Mail in this way?
