Hi,<BR>I&#039m adding a TEXT attachment to an email sent unsing ASP mail. For performance purposes, I do not want to create the text file using the FileSystem OBject, I want to write the email including the attachment. I was able to do it using Mailer.ContentType = "multipart/mixed". Then each part of the Mailer.BodyText start with "ContentType: Text/Plain", the second one becomes an attachment. The only problem is that my attachment has no name. Outlook gives it a "ATT00XX.TXT" name but I would like to control the name myself. Any Idea how to give it a name?
