	Open mail relay - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-21)
		An open mail relay is an SMTP server configured in such a way that it allows anyone on the Internet to relay email through it.
		However after spammers started abusing open relays to forward their own messages, it became frowned upon by some members of the Internet community to run such a server.
		The most famous mail relay is probably that of John Gilmore, who argues that running an open relay is a free speech issue, and that since he has never sent any spam personally he has a right to configure his computer however he pleases.

	Open mail relay - Wikipedia, the free encyclopedia
		The most famous open mail relay operating today is probably that of John Gilmore, who argues that running an open relay is a free speech issue.
		His server is included on many open relay fllists (many of which are generated by "automatic detection", that is, by anti-spam fllisters sending an (unsolicited) test email to other servers to see if they will be relayed).
		Along with his further deliberate configuration of the server, his open relay enables people to send email without their IP address being directly visible to the recipient and thereby send email anonymously.

	open relay - a Whatis.com definition - see also: insecure relay, third-party relay (Site not responding. Last check: 2007-10-21)
		By processing mail that is neither for nor from a local user, an open relay makes it possible for an unscrupulous sender to route large volumes of spam.
		In the past, open relays were used intentionally, for example, to facilitate mail relay between the separate closed e-mail systems (such as UUCP or FidoNet) or to allow network administrators to debug mail connectivity issues and route mail around known problems.
		By relaying mail through several open relay mail servers at the same time, it is possible to flood the Internet with large amounts of junk mail in a very short period of time before being detected.

	Open Relay Database - FAQ (Site not responding. Last check: 2007-10-21)
		An open mail relay occurs when a mail server processes a mail message where neither the sender nor the recipient is a local user.
		The Open Relay Database can be used by anyone in the configuration of their own network or mail relay, toward the goal of limiting theft of resources by spammers.
		When mail is relayed through a mailserver which causes it to be listed in the ORDB.org zone, we store the headers of the relayed mail in a database so that the administrator of the misconfigured mailserver can see how it was possible to trick his/her MTA into relaying.

	The qmail newbie's guide to relaying
		In the first case, your server is acting as a relay: it's accepting and agreeing to try to deliver a message that's not destined for a domain that your server hosts.
		An SMTP server is an "open relay" if it agrees to relay mail no matter who's sending it--if another host connects to port 25 with some mail, an open relay will accept and try to deliver it no matter what its destination is and no matter who is sending it.
		Unlike many relay testers, this one requires that its probe message actually be relayed back to it in order for it to determine that you're an open relay.

	Open Mail Relays
		A complaint concerning the activity of an open mail relay is evidence of configuration that results in a violation of the policies governing the use of these resources.
		Complaints regarding open mail relays (OMR) are classified as security issues and should be reported to the Network Operations Center (NOC) at noc@cornell.edu.
		The system administrator will be informed that a block of outgoing/off-campus mail from the offending OMR could be implemented at the discretion and request of Security staff at any time after verifying the existence of the open relay.

	Change in Open Mail Relay Affects Some E-mail Users (Site not responding. Last check: 2007-10-21)
		Open mail relays such as Ohio State's are SMTP (Simple Mail Transport Protocol) e-mail servers that allow any Internet host to "bounce" mail through them to other Internet mail addresses.
		Other Internet hosts can fllist servers that allow open relaying, which means that they will not accept any e-mail, legitimate or otherwise, coming from or through those servers' domains.
		When we stop open relaying, Ohio State will be dropped from spam fllists and the university will be able to return to more consistent e-mail delivery to all sites.

		If you don't allow relaying based on authentication (STARTTLS or AUTH) then there are basically three slightly different logfile entries which can give a hint about the possible problem.
		If the host name would be used, it would be simple to circumvent basic anti-relaying checks because the PTR records might be under the control of an attacker, so he can chose any name he wants for his IP address.
		That is, he can select a name for which you allow relaying because that name is one that you control (your domain name).

		The relaying of Junk/Spam email is caused by disreputable people using other peoples mail systems to send their unsolicited advertising thereby ensuring that the relaying system is blamed for the email rather than the original sender.
		Once an open mail relay has been identified by a remote 'hacker' they will then send huge volumes of mail through the server until it either crashes or is shutdown, this has a number of direct effects:-

		Open Mail Relay allows e-mail servers to accept and route mail from and to users and networks not associated with the server's domain.
		There is convenience attached to this and until April 30th of 2000, CSUS did not restrict Open Mail Relay services.
		Thus, it was decided by a group of campus-wide program center administrators, faculty, and staff representatives that CSUS e-mail servers restrict Open Mail Relay services and only accept outgoing mail originating from or incoming mail addressed to CSUS resources.

	Allowing Relaying in SMTP: A Series of Surveys
		The results show that fewer than 1% of mail servers that are named in mail addresses allowed relaying in August 2002, a very sharp reduction from over 6% from a year and a half earlier.
		This is the place where most SMTP servers that do not relay are expected to return an error code because it is the first place where the SMTP server can be sure that the message was not meant for local delivery to the system.
		The most likely is that the hosts named in the addresses of the mailing lists are no longer around (some of the mailing lists have not had messages sent to them for many months).

	CommuniGate Pro: Protection
		The Server can relay mail sent by anybody and addressed to a server with a network address included into the Client IP Addresses list, but it can also check if the message address is a "simple" one.
		To avoid problems with old mail servers that ignore the quote marks in addresses, the addresses with the local part containing quotes cannot be relayed to Client IP Addresses servers if the "simple" option is selected.
		This is done because the host to which the rerouted message is relayed may "trust" all messages that come from your host, and relaying addresses with multiple routes would allow someone to relay messages to anybody through your host and that other host.
