I want to whitelist the emails I get from an MSN group [they are sent to a Hotmail address of mine, and I pick them by mail collecting]
I tried whitelisting @groups.msn.com , but it doesn't seem to work with this

groups.msn.com doesn't work because, if I understand correctly, the mail does not appear to come from msn.com but rather from the submitter of the post. I think one way of solving this is to look in the headers for the msn server that is forwarding/sending the mail and add that to your whitelist.

Look for a common "Reply to" address and try that.

Also, lose the @ sign at the start of the white list entry. It will cause failures all by itself.

I thought I already did so, as I whitelisted groups.msn.com that's in the reply-to.



Maybe that's it! I'll give it a try!
Thank you!
