Sure - I was thinking that they originated from my
server, but I did say that my brain refuses to go into gear
today

I think I should ignore this for today.  That address
(192.168.0.7) is a dhcp address, which must have been
my laptop wifi connection, and since I had no wired
connection at the time, if there had been anything really
wrong I wouldn't have been able to use my mail, and I
would have known about it.

It probably represents a fleeting problem.

Since it's the router, the commonality seems to rule that
out.

Did I ask something similar?  I don't recall - but then I
don't recall what I had for breakfast yesterday.  I'll look
back and see if I can find anything.

All the same, thanks to your breaking my circle of
thinking, I don't think there's really a problem.  If it
occurs again I'll look more closely.

BTW, your reply-to plays havoc with normal list
behaviour.
