It is worth mentioning thatBFTP (Basic File Transfer Protocol) client is defined by STANAG-5066 Annex F.10.2.2, that same Annex also defines the Compressed File Transfer Protocol client (CFTP) that provides the most bandwidth-efficient exchange of data just using BFTP (MIL-STD-188-141B Notice 1 APP.E).
Talk about e-mail and file-transport protocols go beyond the purpose of the blogso I preferto have an HF approach, keeping in mind that STANAG-5066 is designed for running IP applications over HF and that the stuff (in this sample) is arranged as in pic. 1.

The contents of 000_HBFTP--3 can be saved to a file and Windows assigns the .eml extesion sincethe file exhibits all the features as it was received from a conventional SMTP server via an Internet connection (pic.5). The file can be opened and processed by Microsoft Outlook w/out problems: Outlook simply does not care where and how this file has arrived (pic. 6). For reasons of confidentiality the email addresses have been deliberately blackened.
