Spammers often like to use a dictionary type of attack to reach users’ Inboxes. You have probably noticed that most spam now appears to come from your own email address.

Most Common Support Issue: Whitelist = Spoofed Spam
No one likes to see spam in their Inbox, especially when it comes from themselves! Users often get confused and even worry that their identity has been stolen.

Users do not realize (or understand) that spammers can spoof their email address and send spam that appears to be from themselves. (May 14, 2010)
Think you don’t spam? Think again!
Who has never sent email spam?

Maybe you sent a message for your business using a large contact list grabbed on a corporate email with a multitude of CC’d addresses? Or did you ‘borrow’ the customer list from work for your own use? (Oh, that’s bad!) (May 05, 2010)

(Un)subscribe me
Hundreds of emails get blocked daily by your spam filters, but sometimes one slips through. You look it over and it appears to be very legitimate.

Yeah, it’s true: XYZ company is one of our partners, we do their mass mailing and we grabbed your address at the same time!” So, now you’re tempted to click the Unsubscribe button, but how can you tell if it’s legit? And how do you know that clicking unsubscribe won’t tell the spammer, “Hey I’m alive and I actually read what you sent - send me more”? (Mar 17, 2010)
Who’s minding the store at WHOIS?
WHOIS (for those unfamiliar with it) is a system that provides free public access to domain name registration. Every domain name has to be registered with the following information: the registrant’s name, an administrative contact, a technical contact, and the name servers associated with each domain name.

Blocked by RFC-IGNORANT ... Now what?
From time to time, customers wind up getting blocked by a seldom seen blacklist called "RFC-Ignorant." Unlike classical blacklists that are usually honeypot driven, this one is driven by people who have manually reported you as violating RFC. (Jan 22, 2010)
