I've a customer that necessity to have all their email directed to an mail-server that they have onsite at their offices. The customer sent me the IP address of mail-server and I have change these values in DA:

1) I have unchecked, in "MX records", the checkbox of "Local Mail server";

2) I have change, in "DNS Management", the IP address of "mail" with IP of "mail-server onsite" of the customer.


is correct ? Is necessary change another values, for example "pop" ?

In the web-site is present a "contact form" that send the request to database and email (with smtp)... smtp will work still good or not ?

thanks
 
You should also change the MX record (if it points to mail and you've changed the A record for mail, then you've done enough).

You may want to change other A records (for example POP) if your client needs to use it (for example, pop.example.com) to point to their external mail server.

in "MX records" panel I must insert the IP address in "Add another MX record" with value "10" and click on "add" button and delete the old value "mail" (see the screenshot) ?

thanks

Not the IP address but the host name.

where I found the host name ? the customer sent me only IP address ...


the customer have a website www.customerdomain.com and would like receive email from mail.customerdomain.com (same domain of website) but the email must be sent and storage in another server onsite at their offices (server configurate with only IP address, not Internet domain).

Hey,

Ahh, I see. I think! You;re keeping all the domain part the same just sending it do a different box... Which is the IP address the customer gave you.

The IP address would be for "mail.customerdomain.com".

I believe you would still need to uncheck the local option.

Yes, you can uncheck the local email option and change the ip address for mail to point to the IP# the customer sent you.

mail feed

I have been asked by my cleint to direct all the mail for a domain to a static IP address....

In practice I would like to do the same for a client, that is, create an mx recored which directs mail to there own mail server.

However, as their connection is ADSL and can not be relied upon, what happens when the line is down? where will all the mail go, which is not delivered? Is there a way of overcoming this problem and is it as simple solution?

many thanks
Richard.

p.s. hi Jeff
 
if adsl is down they can't send mail, they can't receive mail

mail goes spooled on the last smtp, there is no problem about that case so long server retries.
They can order a mx backup to spool but not a good idea if they're already targeted with spam/virus

Best were they have internet servers like yours with DA, and have an intranet server which relays out to yours, and pop all 10 minutes (sample)
Then just add their ip to spf, and make them auth to smtp.

ip static is better but in this last case dynamic ip is enough
 
That's one person's opinion :) .

My opinion is to use a domain name (or a service name such as xmail.example.com) with a dynamic DNS provider (for example Dynamic Network Services, Inc. and then create your local MX to send all email there.

Don't forget that if you use a service name (similar to a subdomain, but doesn't have to be set up anywhere as a subdomain) you'll need to set up NS records for it in your zone file for the domain, or else resolvers won't know to find the dynamic DNS provider.

Dear all,

dynamic ip goes rejected by a lot of server, so it's necessary to auth on a true internet mail server with correct dns aso (can be a MX relay).

That's not only my point of view !

I understand the first part OK and the dyndns service looks ideal. However not sure I follow the second part e.g. service name.. that confused me.

can you provide an example? sorry your having to spell it out.

many thanks
 
Today is the first time I've used the term servicename on these forums, so you're excused :) .

for example:

mail.example.com

You might think of mail as a subdomain name, but it's not. It's the name of a specific service.

Does that help?

Jeff
 
You're very welcome.

At some point in the near past I decided that mail, etc., aren't really domain names or subdomain names, they're servicenames, representing services for a specific domain.
