/*
* RMAIL -- UUCP mail server.
*
* This program reads the >From ... remote from ... lines that UUCP is so
* fond of and turns them into something reasonable. It then execs sendmail
* with various options built from these lines.
*
* The expected syntax is:
*
* <user> := [-a-z0-9]+
* <date> := ctime format
* <site> := [-a-z0-9!]+
* <blank line> := "^\n$"
* <from> := "From" <space> <user> <space> <date>
* [<space> "remote from" <space> <site>]
* <forward> := ">" <from>
* msg := <from> <forward>* <blank-line> <body>
*
* The output of rmail(8) compresses the <forward> lines into a single
* from path.
*
* The err(3) routine is included here deliberately to make this code
* a bit more portable.
