iNotes / Domino Web Access: Missing Attachments

An iNotes user recently submitted a request for assistance. Previously he had been able to receive messages with .txt attachments in iNotes without any problems. However, lately he and a group of colleagues have been receiving the same periodical message but without an attachment icon to indicate an attached file. Instead the .txt file appears in the body of the message as a link. When the recipient clicks on the link to view the contents of the .txt file, they can view the contents within a web browser without any problems. However, if the user forwards the message as is, then others cannot view the contents of the "attachment" because it is now a database link instead of an attached file.

Comments:
It may have to do with the smtp client used to send the e-mail messages.
