You cannot use backslashes in regular expressions.
(Well, at least in milter-greylist 2.x, but I think
it didn't change in 3.x.)

As explained above, you should remove the backslash.
No other TLD ends with "fr", so it should be OK.
If you're paranoid, you can use /.*[.]fr$/ because
the "." loses its special meaning inside "[]".

Note that it is not recommended to match by sender email
addresses, because they can be easily forged (and in fact
they _are_ forged in many -- if not most -- cases of
spam).

If you want to check the TLD of the sending MTA, you
should better just write:

acl whitelist domain fr

The "domain" keyword performs a suffix match on the domain
name of the connecting MTA (as resolved by sendmail).
