Your system reports on port 25:
220 necom830.cc.titech.ac.jp Sendmail 5.65+/necom-mx-rg ready at Wed, 26 Oct 94
01:28:27 +0900
Is this version of Sendmail 5.65 patched to support NULL correctly, as the
standard requires? And more importantly, how do you propose to get all the
OTHER sites that are running *NON* patched sendmails to upgrade? It took
a number of big security scares to get people to move from 5.6x to 8.6,
what will be their motivation for moving to 8.7?
Platitudes like "We should have" are nice - but we have to be pragmatic here.
There's a large obstruction known as "the majority of the user base is broken",
causing a "de facto" 1..127 standard and a "de jure" 0..127 standard. Feel
free to send NULL all you like to "implementations that should handle it".
Just don't be surprised when your mail gets mangled...
