	Understanding MX records :: BobCares :: Outsourced Web Hosting Support
		MX records are used in DNS records(or Zone files) to specify how email should be routed.
		The MX record shows that all emails @ mydomain.com should be routed to the mail server at mydomain.com.
		If all the MX records are equal Preference numbers, the client simply attempts all equal Preference servers in random order, and then goes to MX record with the next highest Preference number.

	MX record - Wikipedia, the free encyclopedia
		If no MX records were present, a second request is made for the A record of the domain instead.
		The MX mechanism provides the ability to run multiple mail servers for a single domain and the order in which they should be tried, increasing the likelihood that mail may be delivered and providing the ability to distribute the processing of incoming mail across multiple physical servers.
		The MX mechanism does not grant the ability to provide mail service on alternative ports, nor does it provide the ability to distribute mail delivery across a set of equal-priority mail servers by assigning a weighting value to each one.

	Processing MX Records
		The preference in this MX record is 0, versus 10 for the second MX record.
		That machine name is to be processed (at the time the line is read) using the recorded MX records and the up/down status of machines to determine how mail to that machine should be directed.
		MX records are not to be processed recursively.

		The MX records tell external mail servers which internal mail servers to use for mail that is addressed to @domain.com.
		First of all, in order for the mail servers specified in the MX record to accept mail on behalf of all of the systems on your network, they must be explicitly configured to do so.
		Also, by using MX records for every mail server on the network, you are gaining a tremendous amount of flexibility, redundancy, and overall reliability, through the use of "preference" values.

		Each line in the zone file is primarily composed of three parts: the name of the record, the type of the record, and the data that define the record.
		The MX record specifies "mail.berrett.org" as the mail exchanger for the "berrett.org" domain name at a preference value of 10.
		In most cases, the MX record we have set up for you will be all that you need.

	Web Server Manual - MX Records and Email Issues (Site not responding. Last check: 2007-09-26)
		An MX record is the record for a zone (domain) that specifies what machine serves as host for that domain's e-mail.
		By default MX records are set up to take advantage of the advanced email system built into each account.
		If the MX is pointing at the correct hostname and that hostname points to the right IP address, then it's time to double check your mail server's configuration.

	RMX Records
		records are intended to make email forgery difficult by providing a mechanism for a domain owner to list all mail servers authorized to send email on behalf of his or her domain name.
		records is that they add to the technical infrastructure governments will have at their disposal to apply legal and economic pressure to would-be email forgers.
		records, a domain declares that it has already provided all of the remote access facilities that it intends to provide, and that therefore any other email claiming to come from it should be treated as a forgery.

		MX records are far more important than they sound.
		A lower number in an MX record means a higher priority, and mail will be sent to the server with the lowest number.
		It is also a good idea to include an MX record even if you are having mail sent directly to a machine with an A record.

		MX records serve a specific purpose: they let you specify the host (server) to which mail for a specific domain should be sent.
		It is important to note at this point that in order for backup MX records to work you must have an explicit primary MX record, even if that record points to the "parent" host.
		When there are multiple MX records, the preference number is used to indicate in what order the mailer should attempt deliver to the MX hosts, with the lowest numbered MX being the one to try first.

	How many MX records should be available in DNS? (500)
		The first two MX records would have equal preference values, allowing mail to be delivered in a round robin style across the two machines.
		The remaining two MX records would be set with a higher preference value in case the first two did not respond.
		Have one MX record specified with one ePrism assigned to it.

	DNS Resource Records
		Each MX record specifies a domain name (which must have an A record associated with it) and a priority; a list of mail exchangers is then ordered by priority when delivering mail.
		MX records provide one level of indirection in mapping the domain part of an email address to a list of host names which are meant to receive mail for that domain name.

	Redundant Mail Relays with Pine, Eudora and Outlook
		Microsoft web site it says that Outlook Express 4.0 follows MX records, and uses the A record only if no MX record is usable, but that OE 4.5 reverses the selection and looks for MX records only if the A record is unusable.
		Both web sites suggest that waiting for MX records that may not exist is tiresome and the vendor is doing a favor for the user by ignoring them.
		MX records, with a different set of rules about same-preference and different-preference servers, and ways to specify those preferences, really are the right way to handle this parallel and redundant server situations.

	Oversimplified DNS - MX (E-mail SMTP server) record
		It MUST have an MX record (not just an A record), primarily because people typically use an E-mail address with your domain name ("joe@example.com"), not a subdomain ("joe@mail.example.com").
		The MX record is a domain name, so the SMTP server then gets the A record for that domain name, and connects to the mail server.
		If there are multiple MX records, the SMTP server will pick one based on the preference level (starting with the lowest preference number, working its way up).

	The Answer Guy 36: Secondary MX Records: How and Why
		Sometimes the MX record of lower preference, say 20, is an off-site domain.
		They would just add you mail server to their DNS records, listing you as a "less preferred" mail exchanger (an MX record with a higher value than any of yours).
		Some people use these features in their firewall configuration --- they place a higher MX host outside their main network (on the exposed network segment) --- and all outside mail has to hit it first (since they can never connect to the preferred hosts inside due to the packet filters).

	XFOR: DNS MX Records and CNAMEs
		However, if an alias record (CNAME) is used for the hostname listed in the MX record, the sending host might re-write the envelope and redirect the RCPT command to the alias hostname and not the original recipient.
		To be canonical, the DNS entry must be an A record or an MX record.
		CNAME records are not canonical and should not be mixed with MX records.

	Configure MX Records for Incoming SMTP E-Mail Traffic
		MX is a DNS record used to define the host(s) willing to accept mail for a given domain.
		Then new MX Records will be added to their DNS information, pointing to the mail servers, all with the same priority.
		Testing the MX Record configuration is critical especially when configuring it for the first time with a new ISP you don't know that well and so on.

	Fallback MX Considered Harmful (Site not responding. Last check: 2007-09-26)
		I define fallback MX as: listing in the MX records for a domain, at a lower preference than the destination MX host, a host or hosts which do no special routing of mail for that domain, and which are under different administrative control than the destination MX host.
		The traditional justification for fallback MX is so that if the destination MX host loses contact with the world for a period of time, there is only a single host (the fallback MX host) with mail queued for it when it returns, rather than the whole world hammering on its door.
		There may be strange situations when, although the destination MX host is up and running, delivery to it is not possible, but delivery to the fallback MX host is possible.

	DNS Simplified - MX records
		It MUST have an MX record (not just an A record), primarily because people typically use an E-mail address with your domain name ("joe@mydomain.com"), not a subdomain ("joe@mail.mydomain.com").
		[If you have MX records for more than one domain, such as "mydomain.com" and "ihostforthem.mydomain.com", you will need to repeat steps 5b and 5c once for every domain with MX records] First, make sure that all the MX records for your domain point to a domain name (IE, "mydomain.com MX 10 mail.mydomain.com").
		For example, if you have "mydomain.com MX 10 mail.mydomain.com", you must also have a record such as "mail.mydomain.com A 10.11.12.15" (unless the mail server isn't in your domain, such as "mydomain.com MX 10 mail.myisp.com" -- but if so, myisp.com must have an A record for mail.myisp.com).

	Domain Name Management, DNS, CNAME, MX Records. (Site not responding. Last check: 2007-09-26)
		All Resource Records have a TTL [Time To Live], specifying the number of seconds other DNS servers and applications are allowed to cache the record.
		An MX Record has a Preference number indicating the order in which the mail server should be used (only relevant when multiple MX Records are defined for the same domain name).
		This A Record is referred to as a Glue Record, because it doesn't really belong in the Parent Zone, but is necessary to locate the DNS Server for the delegated sub-domain.

	Check MX Records for Email :: Webmaster tools
		Mx records - A mail transfer agent or MTA (also called a mail server, or a mail exchange server in the context of the Domain Name System) is a computer program or software agent which transfers electronic mail messages from one computer to another.
		An MX record or Mail exchanger record is a type of resource record in the Domain Name System (DNS) specifying how Internet e-mail should be routed.
		MX records point to the servers to send an e-mail to, and which ones it should be sent to first, by priority.

	Zvon - RFC 1537 [Common DNS Data File Configuration Errors] - Wildcard MX records
		To cover everything by MX records, the required entries are: * MX 100 mailhost pqr MX 100 mailhost .pqr MX 100 mailhost abc.def MX 100 mailhost .def MX 100 mailhost .abc.def MX 100 mailhost An overall wildcard MX record* is almost never useful.
		The effect of such a wildcard MX record can be that mail is unnecessarily sent across possibly expensive links, only to fail at the destination or gateway that the record points to.
		Whereas overall wildcard MX records should be avoided, wildcard MX records are acceptable as an explicit part of subdomain entries, provided they are allowed under a given subdomain (to be determined by the naming authority for that domain).

		"MX" records are used to convert domains that do not point to any particular host into a Fully Qualified Domain Name, or to route messages for one host to a different host that is running a mail server.
		Without "MX" records, messages to addresses such as this would not be deliverable since they do not include a host name (an "A" record will suffice but there will be no backup if yourPC is down).
		In this case, the "MX" records specify that e-mail for acme.com should be sent to yourPC.

		Answer: ``Distance from H to D'' is defined as the smallest preference p such that H is touched by a preference-p MX record for D, i.e., H has an IP address listed as an A record of a preference-p MX record for D.
		Lotus Notes reportedly stops after two MX records in all cases.) This means that, if all of the lowest-distance hosts are persistently unreachable, there is no guarantee that mail will be delivered, even if there are reachable higher-distance hosts in the MX list.
