“Why is this message in Spam? It’s similar to messages that have been detected by our spam filters.”
Perhaps DKIM would help here.
I’m sure @piecritic would love to set that up 
I’m accessing my gmail account through Outlook 2013. I’ve flagged a few emails from info@discuss.pirateparty.org.au as safe sender, yet anything from this alias still gets caught in spam…
I’ll try setting it via gmail UI directly, and see if it changes anything.
