-/* In the spool file, a host plus port is given as an IP address followed by a
-dot and a port number. This function decodes this. It is needed by the
-spool-reading function, and copied here to avoid having to include the whole
-host.c module. One day the interaction between exim and eximon with regard to
-included code MUST be tidied up!
-
-Argument:
-  address    points to the string; if there is a port, the '.' in the string
-             is overwritten with zero to terminate the address
-
-Returns:     0 if there is no port, else the port number.
