No way! Somehow I think I stuffed it up.

When I have the machine at university, its name is
xxx.elec.canterbury.ac.nz. I don't need it for email there.

When I take it home, I didn't change its name. With
xxx.elec.canterbury.ac.nz, a lot of hosts won't accept email from me
as the name does not resolve outside uni. This is one reason I set
the FROM_HEADER to elec.canterbury.ac.nz - it's incorrect, but it
resolves. But then I can't send email to university :-(.

Perhaps the better question to ask is: what host name does one set
for dial-up networking? Where? Is it ok to change the host name in
ip-up.local?

Does a masquerading host always relay? Perhaps I'm thick, but SuSE asks
the question as "What From header to put into mail and news postings",
which is inconspicious enough, but when that leads to open relays I have
to ask myself whether that is a bug in SuSE's setup.
