Why suddenly a relatively several e-mails have been quarantined with the error “malformed header” in the log?
This applies to all F-Secure Internet Gatekeeper versions when used together with F-Secure Content Scanner Server 6.31. F-Secure Content Scanner Server 6.31 sometimes flags normal e-mails with the error message “Email message is found suspicious. Malformed header field.” This problem has been corrected in the F-Secure Content Scanner Server 6.31 hotfix 2, available for download on the F-Secure Internet Gatekeeper hotfix page.
