I'm a Google Apps admin, and it's a mystery that, anytime I receive a message from just one specific ALIAS or GROUP address (and that I'm a member of that group or alias), it RE-SENDS the same message back me AGAIN, placing a new copy in my SENT mailbox. This results in my SENT mailbox filled with tons of emails I never intended to send. Worse, this is an address I've used to sign up for a ton of newsletters, that I want multiple people to receive.
I'm not sure where to start analyzing this. Here's what I have as conditions and hints:
- I'm the admin on the G Suite account, so I have complete access to change anything. (But, need some ideas or tests to try).
- I've checked and rechecked all my filters, and there is no reference to this alias at all, so it isn't visible.
- At one point I was messing around with some Google scripts/apps[?] - Any chance I could have some long forgotten script that is messing up??
- I've long since attempted and failed to just get all my SENT messages from my main email address to be automatically filtered to my in-box, so I've had to remember the practice of adding a CC to myself to make this happen automatically.
