As you may have noticed the spammers are now sending out blank emails with PDF attachments containing spam. I really do hate these people… I do wonder if email will ever be spam free. Let’s hope so.
Anyway… GFI have not, as of yet, released an update to GFI MailEssentials to help combat this spam problem, but I am told that it is top priority for them at the moment so expect a patch soon!
In the mean time, make sure that your DNS blacklists are up to date and enabled as this helps a lot to block these nasties.
