I want to write howto fight back smtp open relay from mail administrator view ... I used qmail for my mail server so ... Qmail is VERY secure and, by default, it does NOT allow open relaying. As a matter of fact, you would have to make some intentional and deliberate modifications to Qmail in order to get it to be an open relay. Now the next question I get is "But does the Qmailrocks.org installation allow open relaying?" Again, a simple answer. NO. Qmailrocks.org's Qmail installation, while containing a lot of bells and whistles, is still at it's core Qmail. The Qmailrocks.org Qmail installation does not deviate from or tamper with Qmail's inherent instructions that open relaying is BAD and should never be allowed by default. In the end, the answer to these questions and other similar questions comes down to a questioning of Dan Bernstein himself. Raise your hand if you think Dan Bernstein would be idiotic enough to allow open relaying in Qmail by default. No han...

List SMTP Open Relay, don't take some dirty work ... :p Relaying mail through the servers of a third party is, at best bad Internet etiquette and, at worst, theft of service. This is not just my view but the view of Internet users and service providers worldwide. Many of the larger ISPs, in a preventative move to stop their own customers from spamming others, have blocked customer's connections to any smtp servers but their own. Open relays, in the vast majority of cases, will not hide the origin of your message. Your IP address is visible and all traffic is logged. Still not deterred? Okay. Here are methods of finding an open relay: - find on your mailing list or google :p here are the list you can check on http://www.smtp.tw - check if this smtp server is open relay or not ... http://vancouver-webpages.com/cgi-bin/nph-chkspam Any abuse (testing servers for which you have no authorization) may be reported to your service provider or law enforcement. Just Quick and Dirty Howt...

Here is the short description An open relay (sometimes called an insecure relay or a third-party relay) is an SMTP e-mail server that allows third-party relay of e-mail messages. 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 effect, the owner of the server -- who is typically unaware of the problem -- donates network and computer resources to the sender's purpose. In addition to the financial costs incurred when a spammer hijacks a server, an organization may also suffer system crashes, equipment damage, and loss of business. 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. However, the Internet has expanded enormously since then, and the potential for abuse has...
