Indeed, since ranges like that simply are not supported in regular
expressions. This should work:
/^j10([0-2][0-9][0-9]|300)@example\.com$/ thisaddr...@example.com
Note:
* This expression still matches j10...@example.com even though the
sequence should start at 10001. I can't find a trivial way of
accomplishing such an expression without it getting pretty complex.
If that's an important requirement, consider just generating a static
list. No need to use too complex regexps for strings that can be
enumerated trivially.
* Initial ^ added.
* Final $ added.
* Unnecessary escape character preceding the @ removed.
* Using example.com as example domain rather than domain.com.
