[BLU] E-mail/DNS quuestion

[chy at genuity.com (Chuck Young)]

Using the -v switch (at least with sendmail) should tell you what to type,
as the whole transaction (less DATA) gets dumped.  I'm curious to see if
AT&T is "clamping down", or what.

You and I have talked about this off-line, but I had soem ideas since. If
you try to use the mail command with the -v option, it shows exactly what
it sends and receives.  That might be informative.  After you find out
what machine sendmail is talking to (probably chmls19.mediaone.net), then
try telnetting to port 25 on that machine.  Have you ever telnetted to 25
and impersonated an MTA?  If not, I'll look up what to type; I have it
somewhere.

I think I've mentioned this before. but I don't think I've ever seen
anyone use username at mediaone.net instead of username at hostname.mediaone.net
(for self-hosted mail) or hostname at mediaone.net (for mediaone-hosted
mail).

Any statements referencing Y2K are "forward looking" as they refer to 2000
AD and not 2000 BC.  Otherwise this would be covered by sections 3.2 ii -
3.7.3 ix in the Code of Hammurabi as it refers to defective pottery,
horses, and software.
