Re: [nznog] Xtra filter email with blank From, To or Subject

Not sure if this is news or not, but I hadn't seen anything publicised re this change. My understanding was that blank "from" fields are valid, so filtering this type of email may break other things such as read receipts.

Blank FROM is valid? I'd have considered a Blank Subject as potentially valid, but surely the From: address should be a requirement? I see a can of worms opening here... (As much as I hate blank-content spam) Mark.
