If you base64 decode this you'll see that the user name that nmh is
sending is "zhangweiwu". So it's not paying attention to the login
specified in the .netrc, only to the password. I just checked in a
fix for a problem which I think matches this one. Can I get you to
try building the head of CVS version of nmh to test this, please?
You can check it out with this command:
 cvs -z3 -d:pserver:address@hidden:/sources/nmh co nmh

Once you've done that you'll need to run:
 date > stamp-h.in

and then you should be able to configure and make as usual.

You should note that the username and password are included in the network
transcripts you've been giving. Although they're base64 encoded so it's
not immediately obvious, anybody could trivially base64-decode them. So
you should be as careful about them as you would be with the password

I'm not sure what's happening here. The output of 'inc -snoop' for
the working and non-working versions of inc might be informative.
