Some mail coming in without attachments

It means the attachment is probably tnef encoded and the webmail program 
was probably smart enough to deal with it.

I had a problem once with a braindead M-Sexchange admin who insisted on 
RTF'ing all outgoing mail. The latest MailScanner version does replace 
tnef-encoded mail with its own non-tnef-encoded version, so you might 
want to look into that.
