Re: [WISPA] Reverse DNS troubles

2007-09-05 Thread Japhy Bartlett
Like some other people pointed out, a VPS with it's own IP is
something like.. $45/ mo.

All you have to do is set your email server to forward through a VPS
mail server, and setup the reverse DNS for the VPS.  Check out
linode.com, or any of the other bajillion companies that provide that
service.


And to hijack this a bit:

I've got four domains hosted on a box with one IP - is it even
possible to set up a reverse DNS so that one IP will return multiple
(or the correct at any given request) domains?

I'm having the same problem, with spam filters rejecting some emails,
because the reverse DNS for the IP doesn't return the right domain.
Or does anyone know of a cheap way to buy extra IP addresses?

Cheers,
J

 possible to set up a reverse DNS so that one IP will return multiple
 (or the correct at any given request) domains?


No.

However, remember that MX and SMTP don't have to actually have anything
relating to the domain involved.  So, give the box the name 
hosting.nolimyn.com or something similar, setup the RDNS for the IP address
for hosting.nolimyn.com.

Then, on your other domains, set smtp.domainx.com as a cname for
hosting.nolimyn.com and set the mx record for domainx.com to
hosting.nolimyn.com.


 I'm having the same problem, with spam filters rejecting some emails,
 because the reverse DNS for the IP doesn't return the right domain.
 Or does anyone know of a cheap way to buy extra IP addresses?


That is generally up to your hosting/network provider...However, I can
provide you some extra IP addresses for fairly cheap; contact me off list if
interested.

Re: [WISPA] Reverse DNS troubles

2007-09-04 Thread Graham McIntire
A quicker workaround than convincing your IP provider to set the
reverse for you would be to use a remotely dedicated or co-located
server (or even a cheaper virtual server) to bounce all of your
outgoing and incoming mail through.  That way you could set up
something like mta.yourdomain.com forward and reverse, which all mail
will pass through both incoming and out to make the overzealous spam
filters pass the mail.

To see who is authoritative for the address space, run a whois on the
addresses in question...

If they can't/won't help you (which, given the non-standard connection you
seem to be using, is a real possibility), then you're best off running email
and such services either on a colocated basis or an outsourced basis.

The best way would be to get your upstream to change their reverse 
DNS. (They're the only ones who can do it.)


Failing that, get someone, somewhere else, to handle email for you; tell 
your local mail server to use this mythical other mail server as a 
smarthost, who can make that change. If your users don't send out that 
much email, this should be fairly cheap (on the order of ten or twenty 
bucks a month).

I was afraid of that. These satellite guys are kind of like an onion.
There are layers and layers where no one is sure who to work with or
where to go.

The ip address space is "owned" by a company that is three or four
layers up in the reseller chain (I'm told that they own the dish on the
other end).

Is there no work-around (like the dynamic ip guys or something)? I
hate to get that cheesy anyway

Unless they've properly delegated reverse DNS (and it sounds like they 
haven't) you'll either have to work your way up the chain, or get 
someone else to shuffle your outgoing email.

Sadly, that's just not how it works. Forward DNS and reverse DNS are 
conceptually the same, and from a technical standpoint just about the 
same, but from a managerial perspective (zone roots and who gets what 
parts sub-delegated) they're two different monsters entirely.

Since you are on their network, I would simply relay the email  
through their server,  the lookup will be sent through for server  
which should have a proper rDNS, you may need to set an SPF record  
for the mail server, but that should work  ( I have done it like that  
on a dynamic IP before)

The ip address space is owned by a company that is three or four  
layers up in the reseller chain (I'm told that they own the dish on  
the other end).


Is there no work-around (like the dynamic ip guys or something)?  I  
hate to get that cheesy anyway


Can you tell I'm desperate?!

Gang, I have started having trouble with my customers email  
getting bounced because other servers are checking the reverse  
dns, which fails to resolve to my domain because my network is  
served by a satellite connection (I'm the epitome of rural). Does  
anyone know of a work-around, or do I have to convince my  
upstream they need to change it to resolve to my domain (which  
may be hard to get to happen.). If I have to work with my  
upstream, how should I go about this / approach it. FYI, they are  
ses-americom.com. The company I purchased the domain through and  
who handles the regular dns lookup (domain to ip) says they can  
not help me because the IP is not in their IP address space.
