Keep in mind that any spammer that owns his own reverse DNS (which is not uncommon) can claim to be fred.company.com, and you would allow him to relay through your server. I strongly suggest that you allow the ability to relay *purely* by IP address, and if you wish to prevent anyone from being able to send you mail (by using the REJECT option), do that by hostname, envelope sender address, or IP address. -- These are my opinions -- not to be taken as official Skynet policy ____________________________________________________________________ |o| Brad Knowles, Belgacom Skynet NV/SA |o| |o| Systems Architect, News & FTP Admin Rue Col.
