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. The main cause for this is that they have whitelisted their own email address to bypass scanning for outbound traffic. 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)
SPF woes with third party services … a workaround.
Many people use SPF (Sender Policy Framework) as an anti-spoofing measure. They create an SPF record in their DNS zone for their domain.
