This is an old revision of the document!
First please note that gmail is the official university email system, and as such receives a much higher support level than the “best effort” Physics system.
Having said that, for anyone who wants to forward umn.edu email to Physics….
<note warning> Warning: Do not set up the forwarding above if you already forward mail from physics email to umn.edu, or you will cause a loop and lose mail! </note>
<note> What follows are some outdated instructions on how to tell Google to also forward spam - many people requested this, to avoid having to check the gmail spam folder, but changes made to the UMN mail service during January 2016 causes issues with this approach - namely that any forwarded spam which is then rejected by the physics system causes the umn system to send you a delivery failure message. We regard this as a poor configuration choice by umn, but are unable to change the behavior.
We now recommend not to forward spam from gmail, and instead periodically check your gmail spam folder to make sure nothing is incorrectly categorized. </note> Next, you can optionally set up so that gmail does not put anything into the Spam Folder, and instead forwards on “spam” messages to the address that was set up above.
This is only useful if you don't want to trust gmail's spam detection, or to periodically check your gmail “Spam” folder.
