The triggers work for a while. I can send email, and triggers fire and download attachments. The triggers eventually fail with a 403 error, after usually 1-2 hours, but the time before fail is not always the same. The fact that it works and then fails, strongly indicates to me that there is a token issue. Also, if we have multiple triggers with the same connection, they tend to fail at the same time. I have sent mail with server log to you earlier this day. If somebody has figured this out, it would be nice if they could post their solution/settings.
