PUSH(8)			  BSD System Manager's Manual		       PUSH(8)

NAME
     push -- fetch mail via POP

SYNOPSIS
     push [-4 | --krb4] [-5 | --krb5] [-v | --verbose] [-f | --fork]
	  [-l | --leave] [--from] [-c | --count] [--headers=headers] [-p
	  port-spec | --port=port-spec] po-box filename

DESCRIPTION
     push retrieves mail from the post office box po-box, and stores the mail
     in mbox format in filename.  The po-box can have any of the following
     formats:
	   `hostname:username'
	   `po:hostname:username'
	   `username@hostname'
	   `po:username@hostname'
	   `hostname'
	   `po:username'

     If no username is specified, push assumes that it's the same as on the
     local machine; hostname defaults to the value of the MAILHOST environment
     variable.

     Supported options:

     -4, --krb4
	     use Kerberos 4 (if compiled with support for Kerberos 4)

     -5, --krb5
	     use Kerberos 5 (if compiled with support for Kerberos 5)

     -f, --fork
	     fork before starting to delete messages

     -l, --leave
	     don't delete fetched mail

     --from  behave like from.

     -c, --count
	     first print how many messages and bytes there are.

     --headers=headers
	     a list of comma-separated headers that should get printed.

     -p port-spec, --port=port-spec
	     use this port instead of the default `kpop' or `1109'.

     The default is to first try Kerberos 5 authentication and then, if that
     fails, Kerberos 4.

ENVIRONMENT
     MAILHOST
	     points to the post office, if no other hostname is specified.

EXAMPLES
	   $ push cornfield:roosta ~/.emacs-mail-crash-box

     tries to fetch mail for the user roosta from the post office at
     ``cornfield'', and stores the mail in ~/.emacs-mail-crash-box (you are
     using Gnus, aren't you?)

	   $ push --from -5 havregryn

     tries to fetch From: lines for current user at post office ``havregryn''
     using Kerberos 5.

SEE ALSO
     from(1), pfrom(1), movemail(8), popper(8)

HISTORY
     push was written while waiting for movemail to finish getting the mail.
