Shawn – any progress on this?  The message with the files that Jerry attached in his reply to you got blocked by my MailScanner gateway (I just noticed that today).  Did you receive them?  If not, you’ll have to get them via ftp or something.  If you did receive them OK, have you had a chance to work on the issue?

I will study this and see if I can assist.

Do you have a sample document with this .dat embedded?

Has anyone dealt with this? I can’t decide if I should mod the source or just change the configs:

- Microsoft document comes through with some sort of dat file embedded. While MS see that dat file as text/plain, the character set is binary, so it nails it as an executable.
- Allowing executables will allow the file.

So, there’s the rub. Under the current code we have to allow executables for these “newer” types of Microsoft documents to get through. This isn’t restricted to just Microsoft. There are several other file formats that make MailScanner fire on this.
