Dear Maintainer,

The French ISP Orange have change their outgoing mailservers,
according to my logs, they now use smtp\d+.smtpout.orange.fr.

They added the 'smtpout' subdomain, so the current entry in whitelist_clients
does not match them.  orange.fr is a big pool with million of mail addresses.

I suggest replacing the current line:

    /^smtp\d+\.orange\.fr$/

with the following one:

    /^smtp\d+\.smtpout\.orange\.fr$/


Another customer complains that his mail cannot get through our mail servers.
We are missing an entry for the Luxemburg' Post Office mail service.

I suggest to add an entry in whitelist_clients for pt.lu:

    # post.lu (big pool)
    /^mailout\d+\.pt\.lu$/

(My logs contains mailout1 through mailout4, but they may add other servers.)

Many thanks,
Cyprien
