Well, I found a number of sites with options on how to combat joe jobs, none of them actually fix the problem to where they stop sending e-mails, it's pretty much impossible. &nbsp;The SPF record is a fantastic idea, and we are using a number of RBLs in Xwall, so I'll award both of you points.<br />

These are very good suggestions.

It seems we're being targeted by a Joe Job. &nbsp;I've looked around and it seems theres not much we can do to stop it, but I was hoping you experts here would have some good ideas. &nbsp;<br />
<br />
It seems most of them are being rejected internationally, which we don't send internationally so I've blocked most countries we don't send to. &nbsp;This has really only helped a little bit. &nbsp;<br />
<br />
Any other ideas?

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.
