[Adminsysters] Fwd: Sending from lists.systerserver.net to immerda doesn't seem to work

[Donna Metzlar]

Hi,

I believe it's not a problem of the SPF records but a missing MX record.

Tuxic used to host lists.systerserver.net but these days we host it
ourselves (on Adele).

So I just made an extra record:
MX lists.systerserver.net. 89.106.208.54

This will take a few hours to propogate to all the DNS servers. Let me
know if it was the solution or not.
