Dear Sir,

I make header_check to filter executable attachment:

/^content-(type|disposition):.*name[[:space:]]*=.*\.(bat|cmd|com|exe)/
REJECT Bad attachment file name extension: $2

It take effect to REJECT all:
.com
.com.doc
.com).gif

**How do we do with attachment name :
Document.com REJECT
Document.com.doc ACCEPT
Document.com(any*Character) ACCEPT

Please support.

Thanks you and best regards,
