Hello,
Firstly, scrap the earlier message I sent to the group. I have done a bit
more investigating since, I now think that I understand the source of my
problem, but unfortunately not the fix.

I have a Raq4 with approx 50 sites, all but 2 of them being dot com, net.
The other 2 have dot ie (Ireland extensions), and are both sites that I have
migrated onto my server from existing servers. The problem is, that one of
my clients, www.abc.ie has stopped receiving mail from a couple (not sure
how many) ISP's. I have an an account with one of these ISPs and whenever I
send an email to client@xxxxxx , the email just "disappears". Send from
another account, my own server, hotmail etc. and everything is O.K.

I deleted the site, all users, DNS records and then recreated it again but
still no good. However, I also created another test user, test@xxxxxx , and
when sending from one of the ISP that was having the problem, I then got the
error meesage no such user at abc.ie. Send from another account and its O.K.

This leads me to beleive that the DNS information has not propagated
totally, eventhough I migrated the site to my Raq4 2 months ago. Not only
that, but it seems that the situation is "fluid", in that some of the ISPs
that had recognised the new DNS information initially, do not recognise it
now.

If I do a whois, using say, www.network-tools.com , the name servers all
seem to be correct.  Any advise?

Thanks,
Declan Connolly.

Where was the site hosted before? Are the people trying to email coming
from that ISP? If they still have the site in their DNS, it would be a
problem for their users. Do a DNS lookup on the DNS server of the ISP
that is having problems reaching the domain.

If you post about DNS issues, please post real domain names.

I have now managed to find the old information re: the domain www.gregans.ie
(real name). And by logging in using the old info, I recovered the lost
emails. My question now is, how do I do a DNS lookup of the original ISP,
www.eircom.net . How can this old nameserver information be removed?
Thanks,
Declan.
