For those of you with your own email servers on your own domains.
Help stop Spam and check your email servers regulary.
An open email relay allows spammers to use your email server to send their spam for them, often making it appear that the spam is originating from your domain. This can often lead to your mail server being placed on a blocked/banned list from many legitimate email servers, resulting in your mail disappearing into the ether sometimes without warning.
If you get spam, check the email headers and enter the email domain / IP and most often you’ll find that the mail server has an open relay.
An open relay is just one method that spamers use to send bulk email. Do a google for “bulk email tricks”, “Proxy Abuse” and “Open Mail Relay”.
