The Command Parser how commands in e-mail messages are processed The parser is the part of Majordomo that extracts commands from e-mail messages. In the simplest case it just parses commands, one per line. It can, however, do much more. If a message consists of multiple parts, Majordomo will only process commands in the first body part, and only if it is a text/plain or text/html body part. HTML markup is removed from text/html parts before the commands are processed. Lines beginning with '#' are considered to be comments, and are ignored. Lines ending in a single '\' are joined to the next line. The second and succeeding body parts can be used to supply data to a command. They are referred to by number. For example, this command put LISTNAME /welcome Welcome to LISTNAME <@1 would store the contents of attachment number 1 (the first body part following the one containing commands) into a file called "/welcome". The parser can also process multi-line commands using here documents (see "help here_document" for more details). Breaking long command lines --------------------------- If a command is too long to fit on a line, or if your mail tool is 'wrapping' lines without your knowledge, you may get error messages back from the server. The errors will NOT say that the line was too long, but they will show that parts of the line were interpreted as separate (and incomplete) commands. To fix this, you can "escape" the line breaks: anywhere a space is allowed, you can insert a backslash and a hard return to make the server interpret several lines as just one command. (White space after the backslash will be ignored.) For example: subscribe-set LISTNAME digest John Jacob Whatsisname <whatsisname@example.com> is too long for some mail tools. Instead, making sure the '\' is the very last character on the first line, use this command: subscribe-set LISTNAME digest \ John Jacob Whatsisname <whatsisname@example.com> The parser will reassemble the two lines into one command. Signatures ---------- The Majordomo server will automatically stop looking for commands in the body of an e-mail message when it reaches a recognizable e-mail signature (one that starts with "-- "). However, to make sure that your signature is not processed, you can use the end command. See "help end" for more details. To change what Majordomo expects to find at the beginning of a signature block, read the "help configset_signature_separator" document. All of these features also apply to the mj_shell program.
