Re: Easy peasy mail
As an example, I see gerdesj linked to mail-tester, which was what I was looking for earlier; my simple mail config (with correct DNS, SSL, SPF) gets 9/10; the only thing it lacks is DKIM signing, mainly because I'm not up on that as yet. Just checked the docs, and it doesn't look too tricky. Suppose I'll have a crack at that this week.
Just FYI, natch.
