Com4Mail is a DOS utility that converts a COM file to one with the same functionality, but whose byte values and formatting make it suitable for direct inclusion in an email. It was developed by Juri Krasilnikov.

Identification

The converted files are very formulaic. For instance, they start with ASCII "BEGIN===tfud#of_Com4Mail_file#".

Software

• BBS# 1 → FOR-DOS/COM4MAIL.ZIP - Com4Mail 1.0
• (archived website) → archived copies of COM4MAIL.HA - Com4Mail 1.0 (HA format)

Note: The two "1.0" versions listed above are not the same. It's unclear if they are functionally identical.
