This change in spammer focus has several potential impacts for IMail customers:

  • Mail servers will be seeing spam from places that might have previously been considered a trustworthy source. Thankfully, the Commtouch Anti-spam solution is there to handle these new threats so the overall impact for Commtouch protected servers should be quite low.

There are a number of things that a mail server administrator can do to help ensure IMail is immune to these kinds of attacks.
