Thread: my mailserver ip address has gone awry!

Someone please save me! I am totally lost now.....

A few days ago I asked UH to reset my MX record; I was hosting my own mail server, but moved back to UH.

However, we are now 48 hours past the change and something is wrong but I just can't figure out what.

if I ping the mailserver name it resolves to my old ip (on my server), whereas it should resolve to the UH servers. I have asked friends on three different ISPs and they all resolve to the old ip address. I have accessed the Windows 2003 DNS server in the firm I work for and flushed the cache to force it to lookup the entries -- again it still insists on using the old ip address after a lookup.

If I use an online DNS or MX lookup tool on the web they resolve to the UH mail servers correctly.

I know ISPs cache DNS data, but I am told they refresh frequently (typically daily) and I can't see how three different ISPs can all get it wrong/not update.

UH support say everything looks good at their end.


So what is going on? Any help/thoughts greatly appreciated.

Thanks

David

Hello,

I've testing it on the three ISPs

So what changed?

Hello,

Nope nothing was changed on the server.

Happy to know it is working at your end.

Very strange! I am delighted it is now working, but intrigued as to what was wrong. Maybe we will never know.

Thanks Wilson
