/*
 * Function: pop_open (char *host, char *username, char *password,
 * 		       int flags)
 *
 * Purpose: Establishes a connection with a post-office server, and
 * 	completes the authorization portion of the session.
 *
 * Arguments:
 * 	host	The server host with which the connection should be
 * 		established.  Optional.  If omitted, internal
 * 		heuristics will be used to determine the server host,
 * 		if possible.
 * 	username
 * 		The username of the mail-drop to access.  Optional.
 * 		If omitted, internal heuristics will be used to
 * 		determine the username, if possible.
 * 	password
 * 		The password to use for authorization.  If omitted,
 * 		internal heuristics will be used to determine the
 * 		password, if possible.
 * 	flags	A bit mask containing flags controlling certain
 * 		functions of the routine.  Valid flags are defined in
 * 		the file pop.h
 *
 * Return value: Upon successful establishment of a connection, a
 * 	non-null popserver will be returned.  Otherwise, null will be
 * 	returned, and the string variable pop_error will contain an
 * 	explanation of the error.
