Tárgy: Re: [Exim] relay by IP
Thanks for correcting me.

I understand how the blacklisting is done, but I forgot that the ISP's
differentiate between home and business IP blocks. I do remember reading
that in the rules now. The several times that I've worked with problems
like these, it's been with a business IP.

Sorry 'bout that, Michael J.
