[IMail Forum] File Attachment Filtering Rules Blocking Some Email With No Attachments

[Imail]

I've got Imail Server 7.06 and after this past week of lovely viruses I've decided to set up file attachment filtering.  After reading IM-20010822-DM01 and IM-20011207-DM01 I've got 8 rules to filter 8 file types and forward them to a user that will autoreply with a failed delivery message:   B~name=".*\.exe":bounce B~name=".*\.com":bounce B~name=".*\.bat":bounce B~name=".*\.pif":bounce B~name=".*\.scr":bounce B~name=".*\.reg":bounce B~name=".*\.vbs":bounce B~name=".*\.shs":bounce   The rules do appear to be blocking the entire e-mails as you would expect, but some forwarded e-mails from Outlook and Outlook Express clients are being blocked even though they have no attachments.  Interestingly enough, e-mails forwarded from Eudora clients seem to go through fine.  Any idea why?   In the mean time I have temporarily disabled the rules due to complaints, but it's just a matter of ftping the rules.ima back up there.   Thanks for the help. ~Jonas Boymel
