Fw: Fw: Testing

[Bob at Brisbane]

I have been trying to get onto these lists for a while now but I was unable 
to until David Wolfskill intervened and specifically allowed me in the 
records. Thanks David and others who replied to my earlier problems.

Below this is a cut and pasted earlier message from David that describes the 
problem I faced.

Right.  And I see one message in the freebsd-test@ archive that you sent
to freebsd-test without a Cc: to postmaster@ (as well).

The first message I have that you sent to both was Message-Id
<003801c61982$baa3aed0$0101a8c0 at bob>, which hit mx1.freebsd.org at Jan
15 03:20:37 (UTC).

The reason mx1 gave for declining to accept it on behalf of freebsd-test
was "450 Client host rejected: cannot find your hostname".

And checking:

mx1(4.9-S)[8] host 203.185.225.22
Host not found.
mx1(4.9-S)[9]

Right.  (You may be thinking that "203.185.225.22" isn't a hostname.
While that is, in some senses, correct, it's not especially relevant.
More below.)

Here is a blurb I cobbled up a bit ago:

The SMTP server in this case, mx1.freebsd.org, is set up so that it
requires:

* that the IP address "reverse-resolve" to a hostname and

* that the hostname thus obtained resolve a set of IP addresses, one of
  which must match the IP address of the client and

* the (fully-qualified) hostname given in the SMTP conversation
  (either HELO or EHLO) must resolve a set of IP addresses, one of
  which must match the IP address of the client.

In the case in point (IP address 203.185.225.22, allocated to
POWERTEL LIMITED), the first condition fails to be met.  You have some
options:

* Use the ISP's designated mail relay host(s) (assuming, of course, that
  the machine(s) in question are set up to meet the above criteria).

* Relay the mail off of some other machine that meets the criteria.

* Finally, if neither of the above is workable, let me (postmaster@)
  know, and I can add that IP address to a list of "accepted" SMTP
  clients.  Please note that this won't be very useful if the IP address
  assignment is dynamic.

Since the mail from the Y! account worked, I don't see much point in
going over it.

Peace,
