Yes, I think you ARE being overly critical. How many code regressions
have had to be patched recently in both sendmail and MIMEDefang? Were
those products tested before release? Do you consider their developers
retarded or their testing regimes grossly deficient? I don't.
In 10 years of dealing with GroupWise, since v4.1, I've never seen it
have a problem handling a "-" in a Domain Name. Doesn't mean the problem
didn't exist or that you didn't get bitten, but it's the first time I've
heard of that specific issue.
Obviously, in the major code overhaul between v6.5 and v7.0, this
particular bug crept in. A programmer goofed, and a test case was either
flawed or missing. Happens to the best of products, and I think you're
holding Novell to an unreasonable standard based on a single litmus test.
Personally, as a _collaboration_package_, I like GroupWise. It's not
chained to a single platform or Directory Service, its web interface is
browser-agnostic, its got a pretty good feature-set for the price, and
it's not the high-overhead management pain that Exchange is.
That said, the GWIA is probably the weakest component Agent. I've said
that and more to the developers, face-to-face. Frankly, I'd like to see
them take the SMTP-to-LIN ("LIN" is the internal GroupWise message format)
translation code and make it into a sendmail MAILER program, leveraging
sendmail's adaptability and offering a chance to get rid of GWIA entirely
(unless it's used for IMAP, POP or iCal). They could take the LIN-to-SMTP
translation code and put it into the GroupWise MTA and have it drop the
outgoing message directly into a sendmail queue (since GroupWise Agents
run quite well on Linux).
Who knows, maybe they'll do it. But I'll bet quite a chunk of change
that Redmond would *never* do anything like that with Exchange. Try
running Exchange without being *forced* to use AD for user authentication,
try using something other than IE for the web interface (sorta works, but
crippled), try using something other than IIS as the web server, and try
running any Exchange Server component on anything other than Windoze (if
you succeed, try getting support for it). GroupWise gives you choices in
all those areas.

Given that you've identified a known issue that's fixed in the latest
release, I doubt action_rebuild will solve the particular problem you
started with. However, I freqently front my GroupWise systems with
sendmail/MIMEDefang - I get better anti-spam, and I only have to run
anti-virus in GroupWise System Domains that host Post Offices - I
don't have to bother with it at the GWIA's Domain. Again, GWIA is probably
the weakest Agent, and doing an action_rebuild on inbound mail will
probably completely eliminate "problem" messages.

P.S. No, I *don't* work for Novell, never have. Just setting the record
straight based on my experience.
