    Glad you brought up the RFCs - isn't a proper rDNS entry for a server a requirement?

    It's a "SHOULD", not a "MUST", as it's perfectly legal for an RFC-compliant email system to not have a hostname. Such a system would introduce itself (in its greeting and in HELO to other servers) as "[aaa.bbb.ccc.ddd]" with the actual IP address replacing the placeholders.

    Likewise, it is a "MUST NOT" for rejecting based on not having reverse DNS.

    The latter is (AFAIK) difficult because you can't do binary masks on decimal numbers in zone files, so if you have a zone that isn't a /24 (or /16), your ISP has to about the same amount of work as if they were doing it for you.

    Recent BIND implementations support zone delegation for PTR records on classless routes (i.e., on any number of bits, not just on octet boundaries). Google for "DNS PTR delegation" for some references.

    It takes five minutes to configure the HELO and DNS records to be the same if you know what you're doing. It works, just not the way you wish it works. HELO = DNS or you don't get to send me email.

    This violates the RFC. The only check you can do is for the correct HELO syntax.

    The argument to HELO is supposed to be an FDQN (although an IP-address literal is also valid, but a bare IP address is not). It does not have to resolve, nor does any PTR record have to return that same FQDN.

    Luckily, you're not doing much harm. I ran my mail servers for over a year checking (logged only) for both whether the HELO resolved at all, and if it matched the PTR lookup from the connecting IP. Since I reject for bad HELO syntax, it turns out that the other checks on the HELO argument would reject less than 1% of remaining connections. Greylisting deals with everything that would have been rejected by HELO argument checks, plus a lot more, so that's what I stick with.

    The owner of the IP address, usually the ISP, is authoritative for the reverse zone. It can't be arbitrarily manipulated without gaining authority over the zone anymore than a forward zone could be manipulated.

    So, what you're saying is that because so many ISPs provide some sort of default reverse DNS (host132.newyork.example.com), then choosing to reject e-mail based on the lack of a PTR record will not only lose legitimate e-mail if the ISP doesn't create a default, but also only rarely block spam.

    Amazon would collect and remit the payment to State B. Sales tax is collected against where the customer is at.

    Apparently, you didn't read the post you replied to, in which there is some question as to "where the customer is at".

    If you pay Amazon with a credit card that has a billing address in New Jersey, but have the order shipped to a verified address in Texas, where is "the customer"? If they are in Texas at the time the order is made, then Texas (state "C" in the OP) has a strong case for the customer being there.

    Likewise, I pay for purchases from Newegg using PayPal, so Newegg has no clue where I "am". All they know is that they are shipping to an address that PayPal has verified I have some kind of control over. Newegg doesn't know if that's my legal state of residence, nor do they know if it has anything to do with my credit card billing address. In this case, Newegg could not send money to state "B", because they don't know anything about state "B"...they only have information about state "A" (where Newegg is) and state "C" (where the order is being shipped).

    The reason this becomes important is that states with more permanent residents (and thus more likely to have credit card billing addresses associated with them) might argue as you do (that state "B" should get the money), while states with more transient residents would argue for the shipping address controlling the payment.

    You don't know whether they have any trouble or not.

    I would not be surprised to see them fail a detailed audit of their tax collection, even though any mistakes might be minimal. The various governments probably don't care as long as they see tax money coming from WalMart, and it seems to be in the right ballpark. They might even "cheat" by pretending that online orders are actually local purchases at the nearest physical WalMart in the same state as the purchaser, thus meaning they don't have to worry about all the tax jurisdictions they don't already deal with.

    The big issue with tax on mail-order or Internet purchases is that although databases exist for the sales tax rules, those databases all assume that the end user inputs the jurisdiction(s) as a constant that applies to every transaction (since the stores don't move). And, it's easy to know what jurisdiction your store is in, because it's a one-time question. But, there are no complete databases that contain every address in the country mapped to the sales tax jurisdiction, because there is no need for them. Even if you went to your local government, they might not be able to correctly answer the question of "what sales tax should I charge on sales at __RANDOM RESIDENTIAL ADDRESS__?"

Yes, you are still going to have the "Angry Birds"/Beatles effect, where there are huge hits that skew the average, and you will have content that will be ignored. But, you no longer need to be able to convince some big company executive that your content will appeal to millions of people just to get it produced and available for 99% of people to reject (because all but the biggest "hits" are still only consumed by a tiny fraction of the population).

This gives you an easy to maintain, reliable backup system. And, if you still need your crutch, you could back up the rsync copy to tape.

    That depends on the hosting company. If they let you load any OS, then maybe, but if they provide you with a clone of their standard image, then only the changes made by the customer need to be backed up...any "full-image" restore would start by restoring from the source image.
