Reverse DNS problem with sending mail to AOL
ao
Sorry that I have to contact you directly. I saw this
your posting on the problem you had with AOL, which I am
facing at present. I have tried all possibilities but
still can deliver to AOL. The latest effort is to ask my
ISP to add an MX record for our exchange sever
(mailserver.domainname.com), so that we will at least
have a public IP reference the what we are using
internally. The only thing though is that we are not
permanently connected to the Internet, thus we do not
have a Public IP directly on our internal Exchange box.
All the DNS records are pointing to our ISP server where
both our mails and website are being hosted, we only
connect at interval to fetch them with POP3 connected.
Going through postings showed that we took the same
steps, only it did not resolve the problem in my own
case. So my question is, is your Internal Exchange on a
Public IP or you have your mails being hosted outside as
well. Or is there anything I have done so far in respect
of DNS.
Regards,
ao

Ok, I'm running E2K SP2 on W2K server and all has been
fine. Now, all
of the sudden we can't send mail to AOL only. We have
made no changes
but they say that our reverse dns is not setup right. Our
mail server
is named company_mail.company.com. We have a DNS entry
for the mail
server's IP that resolves to mail.company.com. So, in
our email
header, our real server name(company_mail.company.com)
AOL doesn't
seem to like that and they drop our mail without bouncing
it back.
This doesn't seem right to me, I don't think we have any
exotic setup
here. Would having our ISP add a reverse dns entry for
company_mail.company.com fix this?
Thanks in advance

Just have your DNS provider add another host record for
company_mail.company.com
This should do the trick.

Ok, I had our ISP add a reverse lookup entry for our
company_mail.company.com and AOL still isn't accepting
our mail. When
I look at the header from our Exchange 2000 box, I see
our local
active directory name in there. I think that is the
problem. Our
company's name was taken in the domain hosting so we
added GP to the
end of it for general partnership so on the Net we're
companyGP.com.
Now, our active directory domain is just company.com and
in the email
header our exchange server sends out: Message-ID:
<8E41F6D34390F444BF39E014107B1F2303978446@company_mail.com
pany.com>
Is there anyway to make Exchange 2000 put
@company_mail.companygp.com
since that is our registered Internet domain. Again AOL
is the only
company not accepting mail from us and this just started
2 weeks ago.

Sure you can do that. It's on the SMTP Virtyal Server
prperty page.
Check the tab "Delivery" tab's "Advanced..." button and
put in the
FQDN you'd like it to use.

Thanks, that worked. As soon as I changed that, all the
mail from us
to AOL recipients was delivered. It wasn't sitting in our
queue so how
in the heck did it just get delivered to all the AOL
people after I
changed that?
