# mmime(1)

create MIME messages

## NAME

**mmime** – create MIME messages

## SYNOPSIS

**mmime** \[**-c** \| **-r**\] \[**-t** *content-type*\] \< *message*

## DESCRIPTION

**mmime** generates a ‘multipart/mixed’ message from the standard input, extending, wrapping, and encoding the header as necessary, and replacing lines in the message body of the form

\#*content*/*type*\[#*content-disposition*\] *path*\[\>*filename*\]

with a MIME part having Content-Type *content/type*, consisting of the contents of the file found at *path*. *content-disposition* is optional and defaults to ‘attachment’. *filename* is optional and defaults to the basename of *path*.

The options are as follows:

- **-c**

  Check mode: don't output anything, exit with status 1 if MIME-encoding the message is required, or else exit with status 0.

- **-r**

  Raw mode: don't expand MIME parts in the body, generate a ‘text/plain’ message.

- **-t** *content-type*

  Override Content-Type for the toplevel part. Defaults to ‘multipart/mixed’.

## EXIT STATUS

The **mmime** utility exits 0 on success, and \>0 if an error occurs.
