[SCOOP #RFW-734912]: ldmd.conf template

Donna,

That's very odd.  A hyphen is not a metacharacter in an extended regular
expression (ERE) unless it's part of a character-class expression
(i.e., within square brackets) --- so it shouldn't have to be escaped.
This can be seen by executing the following command:

    regex -s sura-uf-pe6600-1.coastal.ufl.edu 
'^sura-uf-pe6600-1\.coastal\.ufl\.edu$'

The "regex" utility is part of the LDM package and can be used to
test ERE-s.  The argument to the "-s" option is the string to be
matched and the last argument is the ERE.  The command will print
"match" if the ERE matches the string (as it does on my workstation).

What does the command do on your system?

Yes.  The ERE "\.?" means zero or one period.
