Regex How can I accept mail from only one domain in smtp-gated?

Regex to read fixed width numeric fields

I would like regex(es) that can parse right-justified numeric values in a fixed length field with optional leading whitespace. (This is essentially FORTRAN output but there are many other tools that do this). I know the width of the field. Assume the field is an integer of width 5 (I5).
