attachment missing message

I received an e-mail from a contact mentioning an attachment.  I couldn’t see it, so I sent a reply asking about it.  em Client pointed out that there was a missing attachment, presumably from the text.  Very cool if that’s the case.  I come from an environment where I usually started from the attachment and then created the e-mail, consequently I still sometimes forget to attach.

Hi Ali,
thank you for the praise, we’re glad you’re satisfied with the product.
The attachment message is indeed generated if there is a discussion about attachments in the message but none is enclosed.
