ESS 10 droping messages with .txt attachments

Hi everyone,

We just upgraded to ESS 10 from 9.10; everything works just fine, except now that it drops outbound messages which contain a simple .txt attachment in theirs. I have created the exculsive list with *.txt *.doc... , but it still drops. Is there anyone having the same issue or know how to fix this problem? Please advice me on how to fix this. Thanks in advance.




  • Hi,
    please open a support case with F-Secure. Possibly it might me due to a "true filetype recognition" bug. The support has a hotfix that will help you.
  • Okie, I will. Thank you.
