Thanks to Per Hedeland in comp.mail.sendmail, I've tracked down and fixed
the problem. The key was this part of sendmail.cf:
confDONT_PROBE_INTERFACES DontProbeInterfaces
[False] If set, sendmail will _not_
insert the names and addresses of any
local interfaces into class {w}
(list of known "equivalent" addresses).
If you set this, you must also include
some support for these addresses (e.g.,
in a mailertable entry) -- otherwise,
mail to addresses in this list will
bounce with a configuration error.
So, by default, sendmail adds hosts on any local IP addresses to
class W, making all mail to hosts on those addresses get delivered
locally. Disabling this in sendmail.cf solved all my problems.
Hope this helps anyone who has run across this, or will in the future!
