If this problem has been noticed before, please tell me where I can
find a solution to it--otherwise it seems like we've a bug.

A friend of mine has accounts on several types of machine but forwards
all his mail to his NeXT.  I too have a NeXT and accounts on several
other machines which forward to it.  If I send mail directly to his
NeXT, it leaves my mail queue but does not get delivered to him.  If I
send mail from any other account of mine directly to his NeXT it gets
there fine.  If I send mail to his sun account, which simply forwards
to his NeXT, it arrives fine.  Additionally, if I send mail from my
NeXT to a bogus account on his machine, it looks to my machine as if
his accepts it.  Mail sent to the same bogus account from a sun gets
returned with the non-existent user error.  His mail directly to my
NeXT works fine, but other NeXTs on campus have the same problems
sending mail to his machine.

What is going on here?  Any suggestions will be appreciated.

Here are verbose mail transcripts showing what happens with a genuine
user and with a bogus user:
