Any plans to support it in future? Because IPv6 time is coming closer and closer.

IPV6 has been coming closer and closer for the past 10 odd years. I don't see IPV4 being phased out any time within the next 10 years either. That being said I do thing hMail should start to move towards supporting it at some point within the next 10 years :D

Yep, it's sad that ISP's wait for last second before they change to IPv6. My server is now fully Native IPv6 capable. :)

Can you explain why you even bothered to make your server fully IPV6 capable? :)

I was reading an article the other day on slashdot saying that IPv4 is going to run out of addresses around 2010...forcing IPv6 to come into play.

Because i wan't to make IPv6 available in my server early. Before it's too late and because all other programs in my server supports it.

The same thing has been being said since before 2000, usually about two years out. That doesn't mean it won't happen, just that it's like the old story about California falling into the ocean. It will happen, but if anyone tries to give you an exact date, they're blowing smoke.

What an extraordinary statement! IPv6 has been "available" since 1999. See http://www.ceenet.org/workshops/lecture ... sld006.htm

By the end of 2003, about 400 networks were announcing IPv6 prefixes in the global BGP routing table: http://bgp.potaroo.net/v6/as1221/. That's a very small number compared to the number of IPv4 announcements at the time, but still exists.

Contrary to what the IPv6 evangelists would have you believe, IPv6 isn't a magic solution to all problems. It doesn't do many of the clever things that it was originally planned to do. However, it does do one very important thing: Provide an alternative to IPv4 as addresses become increasingly difficult to obtain.

It is estimated that new blocks of IPv4 addresses for allocation by the RIRs will be exhausted in early 2011: http://www.potaroo.net/tools/ipv4/ is the most quoted netric of this. As Geoff Huston is at pains to point out, this has nothing to do with when IPv4 will cease to be used, but simply measures when IANA will no longer have any spare /8 IPv4 blocks available to allocate to the RIRs. He also says that this date is highly dependent on the actual allocations by the RIRS, which in turn depend far more on the big blocks allocated than the smaller ones. That's why the date keeps changing.

What that means is that some (shortish) time later, the RIRs themselves will run out of IPv4 blocks to allocate / assign, and a new ISP that doesn't have any existing IPv4 addresses available to cannibalise / reassign will have no choice but to use IPv6 for everything.

So, what sensible people are doing is ensuring that (A) they have some IPv6 addresses available for their networks now, (B) that their networks can correctly route both IPv4 and IPv6 addresses, (C) that they are conserving their existing IPv4 addresses as far as possible, and assigning IPv6 addresses to new customers, and (D) that their internal infrastructure works with both IPv4 and IPv6 - including routers, DNS Servers and Mail Servers. The clever guys are doing all this now, rather than waiting until the last moment.

I have no idea how long IPv4 will continue to be used - perhaps as long as 20 years. What we do know, though, is that some people are using IPv6 already. It's the default on Windows Vista, for example. Most mainstream routing equipment has the capability already (Cisco, Jupiter, etc.) We also know that at some stage in the not very distant future, a lot more people will suddenly start using IPv6.

It's therefore incumbent on all of us to ensure that our network infrastructure is capable of handling both. I'd therefore urge you to add IPv6 capability to hMailServer soon, so that those who plan to be still using it in a couple of years have the comfort that it isn't a wrong choice now. It's not very hard, BTW. From a routing point of view at least, almost everything operates in a very similar same way to IPv4, with a different format of address.

Kind regards,
William Stucke

I definitivly have to implement IPv6 in the beginning of 2009. Therefore I need a solution
for running the hms in an IPv6 enviroment.

Hello,
We are implementing IPv6 for all our hosting infrastructure. Products without native IPv6 must be replaced next year. So when we want to use hMailServer in the future we need a commitmend, that IPv6 will be implemented soon.

For all who do not believe that IPv6 will be important, please see the presentation of RIPE and statistics wich clearly say that IPv4 address go to end next 1-2 Years.

This meens that ISPs will try to get even more IPv4 adresses from RIRs to have some reserve on stock and the process will be shorter at the end. So 2009 every ISP should be ready for dual stack!

regards
Milan

There will be IPv6 support in hMailServer when there is enough demand from user base. You can vote for the feature in the feature request section if you need it.

If you need some kind of guarantee on delivery dates of anything, you'll have to contact me for a discussion.

Voted. Here: http://www.hmailserver.com/forum/viewto ... =2&t=12841

This is the only thing stopping me from changing over to hMailServer.

I run over email 150 domains, with several thousand mailboxes. I need a reliable MTA solution, that I won't have to change again soon. Postfix and Exim are available on Unix, but I'd rather run a Windows based solution. hMailServer looks like my best bet, but without IPv6, I can't use it.

Well it's slowly climbing up the list.
