Symbolic link to mhmail

Hello all,

I wanted to know how could I make a symbolic link to mhmail from 
/usr/bin/mailx.  Right now doing this gives me the following errors:
/usr/bin/mailx: 1: /usr/bin/mhparam: not found
/usr/bin/mailx: 95: exec: /usr/bin/inc: not found

Because of course mhmail is not in /usr/bin but in /usr/bin/mh so it 
cannot find mhparam which is also in /usr/bin/mh.

This issue comes from the fact that I wanted to use the 
unattended-upgrades package on Debian which uses mailx to send reports. 
Since only nmh is detected as providing a compatible mailx program, 
mailx redirects to /usr/bin/mh/mhmail.

I have not found anything related to this on the mailing list, sorry if 
this issue has been raised before.

Best regards,
