DNS Setting - MX & Website on 1and1.co.uk - Page 2

Just looked and you need a third party util to enable exchange to recieve a pop feed

The A record for mail.mydomain,com and the MX pointing towards that record is the only way to go. Is it possible to put in a ticket for 1and1 to do the changes? Most hosters will be happy to do the odd DNS change

It looks like I've got there. Just seems to take forever for the DNS stuff to work it's way round the world.

For reference, the setup using the 1and1 DNS panel is:

Create a subdomain of mail.mydomain.co.uk
for the DNS of the subdomain of mail.mydomain.co.uk set the A record IP to the exchange server IP
for the main domain of mydomain.co.uk change the MX record from 1and1 to "other mail server" and enter mail.mydomain.co.uk priority 5
Allow an extraordinarily long time for it all to update.

All I have read on dns suggests priority 10 is prioritised?

Personally, to check this perform NSLOOKUP

nslookup
server enter nameservers
set type=a
enter domain

The figure given for DNS resolution is 24-48 hours normally, most of the time it's quicker, sometimes it can take longer

webcrawler2050 · 21-01-2010, 16:29

Normally, however, on a "decent" registra, should beno more than 4 - 5 hours.

**Kymmy** · 21-01-2010, 16:38

4-5 hours for the details to be passed through from a major ISP to major ISP. But for the smaller ISP's/nameservers they suggest it can take 48-72 hours.

VM though have never been longer than 4 hours

I had a reverse ptr set with o2 in their reverse dns zone which took a week before it started resolving

Until I tried it. Some of the changes made while I've been fiddling with the above haven't been picked up by VM's mailservers for at least 12 hours and in some cases 24

Intrestingly I edited the dns of a mates domain to point to my mail server, the domain was in a godaddy account and the whole change took ~20 mins for it to be up and resolving!
The control over the dns records was extensive too, will certainly consider godaddy next time I need a domain!

**Kymmy** · 20-03-2010, 11:48

I normally use DirectNic and thier pro-dns service, in ten years they've only ever had one outage and that was when they upgraded. A bit dearer but I like it.

I do know what you mean about Godaddy though, well impressed but heard bad things a few years ago about thier reliability, nothing since then so you never know they might have thier act together now

Use OpenDNS if you're having problems with DNS resolution and caching. You can force their cache to update if needed so you can test quicker. http://cache.opendns.org for the cache page.

But this thead is about nameserver DNS settings and TTL including the propogation of the settings for hosted domains, not resolution and failure of such
