-An alternative format for the -oMa and -oMi options is [ip address]:port which
-is what Exim 4 uses for output, because it seems to becoming commonly used,
-whereas the dot form confuses some programs/people. So we recognize that form
-too.
-
-Argument:
- address points to the string; if there is a port, the '.' in the string
- is overwritten with zero to terminate the address; if the string
- is in the [xxx]:ppp format, the address is shifted left and the
- brackets are removed
-
-Returns: 0 if there is no port, else the port number. If there's a syntax
- error, leave the incoming address alone, and return 0.
