Title: Domain With Host But Email With SME
Post by: remstrus on October 19, 2006, 06:31:35 PM

Hi

Firstly, please forgive me, I have searched the forums with no luck . . .

I have a domain running with a host (purely for bandwidth reasons) and I also have SME 7 running with a backup of the domain.

What I would like to do is to have the domain running with the host but the email running locally with SME 7.

The DNS is managed by my domain registrar, I change the A records to point to my hosts IP and normally the mx to mail.domain.com

If anyone has any thoughts, I would greatly appreciate it!

Many Thanks

Phil

You have to meet the following conditions:

1) Have a static IP at your home/office to host your mail server. It is required by some RFCs (request for comments) and almost all ISP mail servers automatically reject incoming mail from non-static mail servers.

2) Point your DNS records as (try to avoid CNAME records):

www A x.x.x.x (your webhost IP)
mail A y.y.y.y (your home/office IP)
mail MX mail.yourdomain.com

3) Ask your home/office ISP to provide a PTR record to your IP (for the same reasons stated in 1).

3) Use a SPF record (TXT) to protect your mail server. See this website for instructions/wizard: http://www.openspf.org/

Hi Nuno

Many thanks, I have set my A record for mail to <smeserverip> and my MX to mail.domain.com

I have updated the DNS records and am awaiting the update.

I will also create the SPF record.

Thanks Again

Phil
