[ZendTo] A head's up about the mailing list

I've just fixed the lack of IPv6 in the SPF record. I'm very wary of
updating our mailman install, as there are a lot of lists on it, and
lots of people would be very upset if a "yum upgrade mailman" did
something horrible. I'm not even supposed to be looking after our mail
system any more, I just do the minimum necessary fixes to keep it working.
Let's see if the IPv6 SPF record is enough to keep us going for now. :-/

'Every morning when I wake,
Dear Lord, a little prayer I make,
O please do keep Thy lovely eye
On all poor creatures born to die
And every evening at sun-down
I ask a blessing on the town,
For whether we last the night or no
I'm sure is always touch-and-go.
We are not wholly bad or good
Who live our lives under Milk Wood,
And Thou, I know, wilt be the first
To see our best side, not our worst.
O let us see another day!
Bless us all this night, I pray,
And to the sun we all will bow
And say, good-bye - but just for now!'
