Click Add to add an e-mail server for this DNS zone. Multiple mail server records can be created to enable better e-mail communication.
To delete a mail server record from the list, click the box next to it and click Delete.
If you have multiple mail servers, you can sort them by priority to allow the next in line to become accessible if there is a problem with the primary mail server. The mail server with the lowest priority value (10) receives the highest priority. The priority values start at 10 and are added in increments of 10.
To rearrange the priority values, click the box next to each of the mail servers that you want to change, then click Swap. You can only swap two servers at a time.
