Microsoft Outlook Express versions 5, 5.01, and 5.5 for Windows 95/98/SE, have an interesting bug when an email starts with "begin". From the Microsoft Knowledge Base:
Messages that start wit the word "begin" are received as blank attachments. To work around this problem: Do not start messages with the word "begin" followed by two spaces; Use only one space between the word "begin" and the following data; Capitalize the word "begin so that it reads "Begin"; Use a different word such as "start" or "commence".
Not included as a solution: Use a different email client.
