It looks much like an NFS file locking problem to me. Would you by
chance mount /var/mail (/var/spool/mail or whatever it is called on
the system you are copying from) through NFS from the same machine you
are copying to ?
My feeling is that the cp requests a file lock which hangs the remote
rpc.lockd which in turn causes any incoming request to sendmail to
freeze. I sometimes observe very similar behaviour when the locking
daemon on my Solaris 2.x server gets confused. I usually have to
reboot, deleting the contents of /var/statmon/sm[.bak] (path varies on
other flavours of Unix, see man statd). As for what your exact problem
is, I don't know. I just suggest that you take a close look at NFS
locking on either systems (do the statd and lockd daemons run ?).
Good luck,
_Alain_
