- MX-RECEIVERS EXPLAINED
- ----------------------
- by Burt Juda 1:107/309, July 93
- (in area UFGATE)
-
-
- Machines which are physically connected to the Internet each have a unique
- Internet Protocol address (often called an "IP address"), 4 decimal numbers
- between 0 and 254 separated by dots (ie: my workstation, zeus.ieee.org is
- 140.98.2.1). These numbers are used in the headers of the encapsulated
- packets (all data is broken up into chunks and eack has a header showing
- origination and destination) transmitted over the Internet.
-
- The "Domain Name Service" is a distributed system of having the data at
- different locations and is effectively a "database" of mappings between the
- "names" that machines are known as and their "IP addresses". In order to
- communicate with a system one's machine must get the IP-address of the
- machine it wants to talk to from the DNS first. These are stored in the
- DNS in what are known as "A" records. Machines which have IP-addresses
- exchange "mail" using a protocol called SMTP (Simple Mail Transfer
- Protocol), communicating on port 25 of the set of IP sockets.
-
- However, there are many machines which have "names" but are NOT connected
- physically to the Internet, those doing UUCP and other reasons. In order
- to get mail to such a system, the DNS contains an "MX" record. The "MX"
- record, instead of giving a dotted-quad IP-address, holds the "name" of
- the system which *does* have an IP-address and knows how to get mail to the
- real destination system. An "MX" record *must* point to the *real name* of
- the machine which is accepting mail for the destination system. A machine
- may have several names, but the "MX" records *must* point to it's TRUE name
- (that which is returned by the `hostname` command on a UNIX system). The
- machine which is pointed to by the "MX" record is known as the
- "MX-receiver" for the destination system.
-
- The reason that the "MX" record *must* point to the TRUE name of the
- MX-receiver is that *it* will in turn query the DNS and will compare its
- `hostname` with any MX-records found. The MX-records also have a number
- which is a "Precedence" number. They are tried in order, but always
- skipping any MX-records which point to itself. If the MX-record with the
- *lowest* precedence number points to itself, then it *must* have the proper
- rules in its mailer configuration to deliver the mail via means OTHER than
- SMTP, otherwise an error will result. This means that an "MX-receiver"
- system *must* install the proper handling in its configuration for the
- destination system *BEFORE* the "MX" record is installed in the DNS.
- Otherwise, errors can result, mail loops develop, and the mail cannot be
- delivered.
-
- Here's a couple of examples of the DNS records from .fidonet.org ...
- These are a *PARTIAL LISTING* as examples only.

- ;
- ; ========================== end of example DNS ========================
-
- This is extremely important for the .fidonet.org domain to function
- properly, since the "Hostmaster" (me), maintaining the MX-records for the
- domain is very dependent on all the MX-receivers having the proper
- configurations. Many times, a site will hook up with someone who is
- willing to pass mail/news to them via UUCP, but is NOT physically connected
- to the Internet (does NOT have an IP-address and running an SMTP mailer).
- Now what? This machine may also be a hop or two away from the nearest "IP"
- node in the Path. Now we're dependent on *ALL* of the systems in that path
- to have the proper configurations for handling mail for the new site.
- Mostly, these systems depend on the "UUCP Maps" for their path
- configurations. Now we have a Catch-22 situation. I cannot submit the Map
- until the site is "tested" and the MX-record installed in the DNS. Even
- once I do, it can take weeks or months before the Map appears in the
- Newsgroup comp.mail.maps (fully Moderated and usually comes thru monthly).
- In the meantime, the configurations on all the systems in the dependent
- path are "broken" waiting on that all-important Map for the new site. Mail
- goes into a real "loop".
-
- To add insult to the whole process, the system names contained in a UUCP
- Map (which most new sites will construct and send me) do NOT contain the
- "Fully Qualified Domain Name" (the dotted name) of the systems they connect
- to. Now it becomes a matter of guesswork to see if any of the site(s) they
- connect to have an IP-address and can qualify as an MX-receiver.
-
- For the reasons outlined in the last two paragraphs, it is essential for a
- new site to hook up with a system that has an IP-address and can act as
- their MX-receiver. It's much easier if the proper Map procedures were
- followed and their UUCP Map submission contained the proper "#F
- mx.receiver.domain" line in their Maps, giving me the
- Fully-Qualified-Domain-Name of their MX-receiver.
- It's bad enough that I have to hand-edit each and every Map submitted,
- because our wonderful FidoNet editors expand TABS to spaces and the
- submission I send to the UUCP Map Coordinators *must* contain the proper
- TAB separators, not spaces!
