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 sin-
       gle 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.
