Emails with multiple recipients only showing up to one recipient

[mpalmer (Matt Palmer)]

Yeah, I misspoke on that one – you can have a single PM topic to multiple groups, so if you wanted to support just that, it could work. Multiple categories definitely doesn’t work, though, so you’re then stuck special-casing the “look at multiple addresses” code to PMs, and then handle it differently for categories. Fun times… fun times.
