I'm trying to reach some people at a particular ISP
, and since I haven't heard from them in some
time, sent email to noc@XXXXXXXXXXXXXX,
just to make sure that
maybe, just maybe,
someone there would notice.
I just got this back:
----- The following addresses had permanent fatal errors -----
----- Transcript of session follows -----
... while talking to mail.XXXXXXXXXXXXXX.:
>>> RCPT To:<postmaster@XXXXXXXXXXXXXX>
<<< 550 <postmaster@XXXXXXXXXXXXXX>... User unknown
550 postmaster@XXXXXXXXXXXXXX... User unknown
Um … RFC-822
has this to say about postmaster:
6.3. RESERVED ADDRESS
It often is necessary to send mail to a site, without know-
ing any of its valid addresses. For example, there may be mail
system dysfunctions, or a user may wish to find out a person's
correct address, at that site.
This standard specifies a single, reserved mailbox address
(local-part) which is to be valid at each site. Mail sent to
that address is to be routed to a person responsible for the
site's mail system or to a person with responsibility for general
site operation. The name of the reserved local-part address is:
so that "Postmaster@domain" is required to be valid.
Note: This reserved local-part must be matched without sensi-
tivity to alphabetic case, so that "POSTMASTER", "postmas-
ter", and even "poStmASteR" is to be accepted.
§6.3 of RFC-822
It's a requirement that postamster exist as a valid email address
for any domain accepting email. So the ISP in question is violating an RFC. Tsk tsk tsk.
You have my permission to link freely to any entry here. Go
ahead, I won't bite. I promise.
The dates are the permanent links to that day's entries (or
entry, if there is only one entry). The titles are the permanent
links to that entry only. The format for the links are
simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are
interested in, say 2000/08/01,
so that would make the final URL:
You can also specify the entire month by leaving off the day
portion. You can even select an arbitrary portion of time.
You may also note subtle shading of the links and that's
intentional: the “closer” the link is (relative to the
page) the “brighter” it appears. It's an experiment in
using color shading to denote the distance a link is from here. If
you don't notice it, don't worry; it's not all that
It is assumed that every brand name, slogan, corporate name,
