You also can't have an SOA record, or any other type of record, on something that's CNAMEd elsewhere. Also, pointing a CNAME at another CNAME, while technically legal (I think), is potentially problematic - you may start seeing glitchiness with some clients, timeouts, etc. Good points. Within this particular context, I'm not sure that a SOA record is that important, but it's worth noting. You're right about the MX record. By standards, a MX record should always point to an A record and not a CNAME. In practice, I'm not sure it actually has an affect on anything. I'm pretty sure, however, that if pointing the MX to the CNAME doesn't work (or is problematic), you can always point the MX to myhostname.someddns.com (which *is* an A record) and your mail for the domain will still go there. It's been so long since I've had to do this that I can't remember if I did that or just ignored the standard and pointed the MX at the CNAME anyway. :-) But I do know that I had no problems getting mail sent to my domain and Postfix handling it on the local Linux box. The danger in this case is not with receiving but with sending emails as some mail servers might mark you as spammer and blacklist you due to dynamic domain linking. That's not a danger associated with doing the above, that's a danger associated with trying to send mail from your dynamic IP address that your ISP assigns you. The two are unrelated. Since it's true that a LOT of places will reject mail coming from consumer IP address space (as opposed to business customer IP address space) within an ISP's range, sending mail from your machine can be problematic at best. I've found that the best way of dealing with that is to use the smart relay ability of Postfix (and I would assume other MTAs as well) and set it up to relay all outgoing mail off of your provider's mail server. That way, the mail coming from you to another service will be coming from your providers mail server(s) and won't block it simply on the grounds that the connection is coming from consumer address space. YMMV, but I've found it works very well. --Dave smime.p7s Description: S/MIME Cryptographic Signature

Domain names typically aren't free, even if you can find a free DDNS service that will handle your domain name (as opposed to them just letting you pick a hostname to use as a subdomain under one of their supported domains). Please notice how the subject line was changed to indicate the branch-off from that original conversation (related, but a segway), per the normal conventions. It says how to use DDNS with your own domain name. If you're gonna pay, choose a registrar that allows you to modify anything about your mydomain.org and supports dynamic DNS. There are a few, joker.com for starters (12 $USD per year seems reasonable to me). No need for DynDNS or similar then. My 2¢ Not every registrar supports DDNS. I'd guess that most of them don't. Since people like to choose who they use for whatever service they use, what I suggested works just fine. If you've *got* a domain already registered to you but don't want to change registrars (which can be a pain) just to be able to use one that has DDNS support, the method I suggested does the job. If you're already ON such a registrar, then you don't need to do anything other than what you're already doing with them, so you wouldn't be in a what do I do about DDNS for my domain situation and thus my suggested solution doesn't apply to you. :-) (That's a generic you, not you specifically.) --Dave smime.p7s Description: S/MIME Cryptographic Signature

If you want to do this trick, you need to create a new name such as www.mydomain.org as a CNAME record. Then there's no problem creating an MX record for mydomain.org pointing to myhostname.someddns.com, which is just as flexible as the CNAME.

Ways to use DDNS with your own domain name (was Re: DynDNS no longer free.)
Rick Macdonald grabbed a keyboard and wrote: [...] I only looked at a couple before deciding to use the free service from ASUS that is included with the router, so I don't know which of the above are actually free. The domain name is not pretty: [yourhostname].asuscomm.com, but that doesn't bother me for my usage. The biggest problem is that if I ever switch to another brand of modem, I have to suffer another change in service and domain name. There *is* a clever (?) hack, of sorts, that can let you still use your own registered domain with one of these other services that just give you somehostname.them.com for free. I used this trick for years before I signed up with DynDNS to use my domain name to point to my Linux box at home. (I'm on a grandfathered plan with them, so I've got a free domain name DDNS with them for life, but this trick should still work.) The trick depends largely on how much control your registrar gives you with your DNS records. The registrar I use lets me edit all records associated with the domain. Here's the example names: mydomain.org myhostname.someddns.com The first is my domain name, and the second is the name being used by the DDNS service. This should be obvious, but I wanted to be complete. :-) So, you set up myhostname.someddns.com and get your updater program running to keep your IP address information current with them. Now, go to the registrar for your domain name. See if they allow you to modify the DNS record for it (I would think that most of them do, but I have no way to know for sure). Assuming that they do, what you want to do is create a CNAME record for the domain - set a CNAME of mydomain.org that points to myhostname.someddns.com. Presto! Now when you try to access your home machine, you can simply refer to mydomain.org and it will point you to the correct place. You can also set up CNAME records for subdomains (whatever.mydomain.org) to point to your DDNS hostname as well. I never had any problems with SSH, Apache running on my machine, etc., while doing this (regardless of what the DDNS service was calling it, my machine always internally identified itself by my domain name, so names matched up). I'm sorry if this is already well-known. I hadn't seen it mentioned, so I figured I'd bring it up. HTH. --Dave smime.p7s Description: S/MIME Cryptographic Signature
