I moved my domain away from my ISP a few weeks back, I moved the domain to mydomain.com and redirected the e-mails to another ISP account.

All well and good, until suddenly today, the whole thing reverts back and e-mail redirection to to the original ISP again !

I checked mydomain.com and redirection is still to the alternate ISP account, I also checked the MX records on Sam Spade and they give mydomain.com ones.

What is happening, I can find no evidence that my e-mails should be redirected to the old ISP. This is extemely worrying as I intend to disable the account next week !!

Is all your mail coming that way, or is it just some? The DNS records for your domain could have been cached at the ISPs where the mail originated from. Try sending from your old ISP account and see where it ends up. Then do a series pf nslookups on the racords of your domains with your ISP's nameservers and mydomain nameservers. We could be more helpful if we knew the domain name.

I noticed that the old ISP still had the domain listed under my account, I have got them to remove it.

I posted again from hotmail and it works fine now, but from yahoo it seems to still be going the old route :(

Crazy crazy crazy.

My old ISP to the domain redirects to the new ISP, the new ISP to the domain redirects to the old ISP !

Yahoo still redirects to the old ISP, everything else seems to be going to the new ISP (correct one) now.

How the heck does this sort of thing happen ?

It's probably caused by caching of the domain DNS records. It should fix itself within a few days.

Many thanks for reply.

Why it is strange is because it's been working fine the last week or so, and stranger as some sources seem to be okay yet others not.

How can I check a particular DNS, for example, how do I check the DNS that Yahoo is using, and Hotmail, etc ?

Can this be anyway linked to my old ISP, they still had my domain listed as being hosted under my old account, could they have somehow "flushed" this information out again and overridden the mydomain.com DNS settings I've had for the last few weeks ?

Thanks again :)

Hello
On a couple of occasions I have found rogue copies of xone files still located on certain name servers.

On one occasion I advanced the serial number for the zone and restarted Bind, this sorted it (it might just have been coincidence though).

On the other occasion I contacted the sysadmin at the ISP and he found an update problem attheir end and fixed it.
