What you are running into is the anti-relaying feature of the MTA at your
wife's office. All well-written mailers provide anti-relay filters these
days, to present spammers and other low-lifes from using the site to
distribute mail. Unfortunately, they cause some friendly-fire casualties as
well, and your setup appears to be one of them. Your purpose is different
from a spammer, but intent aside, the behavior the mail agent sees is
indistinguishable.
When a MTA is running anti-relay filtering, it will accept mail for delivery
only if at least one of these conditions holds:
-- the mail is from an address in the domain served by the MTA
-- the mail is to an address in the domain served by the MTA
-- the mail is from or to an address in a different domain
that has been explicitly included in an "OK to relay"
list.
In your case, you may have Netscape set up with your wife's e-mail address as
[EMAIL PROTECTED]
but work won't accept it for delivery unless it comes from
[EMAIL PROTECTED]
Even if you have that part right, a good MTA will notice that no matter what
the From: line of the message says, the From line (note the absence of the
colon -- From: and From are different in SMTP) says it is from outside.
Since From: headers are trivial to forge and From lines much, much harder to
fake, good anti-relaying software will notice the wrong From line and refuse
to relay.
You can't fix this without the cooperation of the sysadmin at your wife's
work. I can't say what the exact fix is -- that depends on how the office
does its anti-relay stuff -- but the sysadmin will know.
