Thanks Chris

My mail is going to my ISP smart host now, and it seems to work fine so I guess I have no need to change it. Does that mean I don't need to bother with the PTR record?

People here freak if the mail is down for a few hours let alone days. I just need someway to let (some) people get at their new incomming mail and not have the rest bounce as this gets everyone very exited..

I'll take any suggestions on that

remember that a "higher priority" record is actually a lower number for MX records... i.e. 0 is higher priority than 10

make your MX record the highest priority from the get go, otherwise you wait twice...once for the record creation, once for the change in priority

I'd kill that cname record for mail

Unless you think your server will be down for more than 3 days (and remember you can always change the MX record to send mail somewhere esle and the new record will replicate in 48-72 hours) you may want to re-think the backup mx record. But if you really think you need it, and your webhost doesn't, dyndns.com offers it fairly reasonably.

But more importantly, consider sending mail via a smart host rather than via DNS, or you risk getting blacklisted if you wind up an open relay somehow

Hello

We are finally planning on migrating from the POP3 connector to Exchange
SMTP on our SBS 2003 R2 box. But I am not IT pro (just the designated IT
guy), and want to make sure I understand the steps correctly. For this
discussion our domain name is "example.com"

We already have an 'A' record in the form "SBS.Example.com" that points to
the static IP address our our SBS. We use this for remote access.

Please correct me if I am wrong, but all we should need to do is

1 Get our ISP (in our case not the same company that hosts our domain) to
create a Reverse DNS record for our static IP (not sure how this works).

2 Create a new MX record that points to SBS.Example.com with a higher number
priority than the pop service currently has, and wait a few days for the
records to propagate.

3 On the change over day run CEICW and change email delivery to "Use DNS to
route e-mail" and add "Use Exchange (e-mail is delivered directly to my
server)" to the retrieval method.

4 Then promote the new MX record to the top of the heap.

5 Wait a few days then run CEICW again and get rid of the "Use Microsoft
Connector for POP3 Mailboxes" retrieval method.

Is this right?

The only thing I don't know yet is if our domain host offers a backup MX
service. If they do then we could add a lower priority MX record for that
then ditch the old pop MX records?


If we keep the keep our POP3 accounts could this act as a backup service
that would allow us to use there webmail should our server be down for an
extended period?

Do I need to change the CNAME record that currently exists for
"mail.example.com" that points to "mail.domainhost.com" to something else?

Thanks

Terry Mc
