Thanks.
UID 25 is "at". Odd thing is, sendmail made that change with 8.12, and SuSE
loads 8.12.2, then the patches bring it up to 8.12.3. I'd have expected
them to have altered the UID assignment in the default Linux setup so that
it conformed to the requested specs.. If I set it up to the sendmail specs,
I wonder if I'll get some "unexpected behavior" when I run it?

Looked in /etc/passwd and /etc/shadow - both had a * in the service
accounts. Probably easiest to just edit them by hand as the graphical
utility will start UIDs at 500 & go up from there. Thought about
reassigning "at" to UID 24 and adding smmsp in as 25. My inclination is
that won't work, as the file properties point to the UID if memory serves,
not the name so suddenly all the files "at" used to own would be owned by
smmsp. Probably safer to just pick an unused number.
