Conf DNS for mail server with dynamic IP

[Captain Carrot]

Hello,
At work we have a fixed IP connection, and I configured a Linux mail server and an MX record in my DNS to point to the server, what classic. Problem: how in the case of a dynamic IP? ... I like to have a domain name "some" managed by my own DNS server (bind) and with my mail server above. However, I do not see how to configure the DNS? And we ask the ISP to link to our static IP address as the domain manager some, and you're set. But for a dynamic IP? We can not go through our ISP, since theoretically it is forbidden to put a server on a connection with Dynamic IP But as the fixed IP are expensive, and then to test how I know it works. Any help regarding this is appreciated. Thanks in advance.

Hello,
If I understand what you want to do is impossible? I do not know much, but I have not heard of this before. You can do a mail server with the addresses of such [email protected] but that's all? In any case you can have own mail server and an address "[email protected]" with a dynamic IP? So, I think you should look for some other alternative for doing the same.

Hello,
I heard of redirection. I know that it exists for web sites is common for an address "www.example.com" pointing to "some.example.org", is there no way to do the same thing the mail? Because then it would be great, I configure my server using a some.org whatever, and then I should find a way to redirect my domain "some.com" to "some.example.org". If I am wrong then please correct me. Also, if you have any alternate option for this then please let me know.

Hello,
I found it, It's actually very simple, the MX record field does not necessarily point to a machine on the field. So just put
Here is the code which I am talking about

@ IN MX 10 some.example.org.

This trick has worked for me. Please check and see if this is the solution you are looking for. If not then you can try other alternatives also.
