[Mailman-Users] DMARC hack

[Allan Hansen]

Hi Stephen,

Yes, there is a good reason. I’m using Mailman as it came with the OS X Server and am not prepared to replace it. Also, Mailman no longer comes pre-installed on the Apple platform, so I’m basically stuck. This is why I tried the simplest hack I could find. I have 44 busy lists and I’m weary of messing anything up, as I have basically no
time or background to fix it.

Yours,

	Allan

It means the code for doing this is already there for you and will work by looking up the relevant domain's DMARC policy in DNS.  I use it on all the lists here by default now by munging the From: header and it works when it needs to.
