Why does Ultrix 3.1 Sendmail convert uppercase hostnames to lowercase?

[Gregg F. Thompson]

It appears even with the h flag in the F= on the Muucp line in our sendmail.cf
that our sendmail STILL lowercases the host name!  We need sendmail.cf to
work properly and keep the address uppercase (like the entry in our L.sys
file).  Right now with the system names being uppercase in our L.sys file
these sites do not get any mail from us because when we send mail sendmail
converts the upper case names to lower case.  ANY help would be greatly
appreciated!

Thanks!
