What you are doing is essentially correct, but $=Z tries to match any
of the strings in _class_ Z; $Z would try to match the _macro_ Z.  To
define a class, instead of a macro, you can either say

# known DECnet sites
CZvaxa vaxb vaxmate25

or

# read known DECnet sites from a file, one per line
FZ/usr/lib/mail/decnet.sites

or even:
# read known DECnet sites from a file containing lots of information,
# with the DECnet site name in the second colon-separated field (scanf)
FZ/usr/lib/mail/decnet.database %*[^:]:%[^:]

	Good luck!
