I haven't seen the issue of MS blocking lfd messages with the report "Message attempted to kill MailScanner". Are you running the latest version of MailScanner? Is there plenty of space left on your hard disks and partitions?

I am getting this same error on several emails. What should I check?

I'm afraid it's not something we've seen. All I can suggest is running MailScanner in debug mode and if that doesn't give you any clues (errors that you can look into) then you might want to check the MailScanner mailing list.
