This may have changed, but I doubt it. If you do not have MX records there are definitely mail servers out there that will not send mail to you. Exchange for one at least used to refuse to deliver mail without an MX record. I don't know if this is still the case as I am thankfully at least 5 years from having to deal with anyone on Exchange server. -- At night when the bars close down Brandy walks through a silent town And loves a man who's not around
