NAME
       splitmail - Split a large mail message into MIME-compliant partial
       messages

SYNOPSIS
       splitmail  [-d] [-v] [-s splitsize] [-p prefix] [-i  id-suffix] [file-
       name]

DESCRIPTION
       The splitmail program will take an email message and break it up into
       smaller pieces using the "message/partial" type defined by MIME, the
       proposed Internet standard for multimedia mail formats.

       By default it will take the message either from standard input or the
       named file, and will produce a set of partial message files with names
       like "/tmp/split.1" for the first part, and so on.  The prefix
       "/tmp/split." can be overridden using the "-p" option.

       If the -d option is specified, the mail will actually be delivered.  If
       -v is specified, the verbose flag will be passed to sendmail.

       The -i option can be used to make splitmail generate the pieces with
       similar (but not identical) message-id fields, in a format which allows
       them to be easily correlated with one another and which end with the
       suffix provided on the command line after -i.

       The default chunk size for spliting messages is 250000 at most sites,
       though this is also a compile-time option.  This can be overriden with
       the -s switch, or with the environment variable SPLITSIZE.

       Messages smaller than the chunk size will not be turned into partial
       messages, but will be written to a single file or delivered as a single
       message.

ENVIRONMENT
       SPLITSIZE overrides the default chunk size.  Setting SPLITSIZE to, say,
       4000000 will effectively ensure that your messages are unlikely ever to
       be split, but it may cause them to be rejected by some mail transport
       software.

BUGS
       If the size of the input is just on the fencepost, and if it is coming
       from a file rather than standard input, splitmail will sometimes
       estimate the number of parts wrong and will have to write out an extra
       part.  This is harmless but annoying.  It is especially annoying if the
       estimate was 2 but the real number was 1.
