Karma

Fused has recently implemented a spam control system partially based on the concept of karma: Good deeds are rewarded, while bad deeds are punished. Whenever someone interacts with our mail system, either sending to or from, the current karma score for the sender's IP address is noted.

If the spam fighting checks come back clean, the karma for that IP address is increased. However, if the checks come back negative, karma for that IP address is reduced. How much the karma score is affected depends on the results of the spam checks and the current karma score.

The same process happens when Fused customers send email, but with a big karma boost just by properly authenticating with the mail server. With the karma system, no single email is going to cause email to be blocked.

Ensuring your karma scores are positive

Ensure you're connecting using the proper email settings

  • ALL email accounts should have SMTP Authentication enabled, and properly adhere to the Fused email settings.
  • When a user has an invalid password configured for their account, our system sees this as bruteforcing and will degrade a karma score. Change their email account password!

Don't spam / spoof

  • Don't spoof: Send email from the same address used to SMTP Authenticate. (Don't send mail as mary@example.com using john@example.com's password)
  • Most importantly, don't send spam! If you, or one of your users sees a sudden batch of bounceback emails, it could mean your email account has been exploited. Change the email account password to be safe.
