Gradwell's web hosting services include mail hosting. However, if you wish to use a third party mail service instead then you will need to make some changes to your zone file.
You will need to know the MX records that the third party require you to enter into your zone file - this will be their mail servers. If you are unsure of these details then please contact this provider. You can now add these to your zone file - please see this article for assistance with doing this.
When adding your new zone file record select MX using the DNS Record Type dropdown box. The screen will reload and you can enter the details your third party provider has given you.
The following needs to be configured on the record:
- Mail domain: this is the mail domain that you want to use for inbound mail (the part after the @ in the email address). In most cases you will leave this box blank, but if you use a subdomain in your email addresses then you will need to enter that subdomain here
- Preference: MX records can be weighted in terms of preference, allowing you to add multiple mail servers and specify which is the 'preferred' server. If this is unavailable for any reason the other mail servers (if added) will be tried next
- Mail exchanger: this will be the mail server of the third party
- TTL: short for time-to-live. This is how many seconds will elapse before the record is refreshed in the DNS cache - in most cases you can leave this as the default unless your mail server changes regularly
Click Finish when you have completed the record. It will be added to your DNS records list
If you plan on using the third party mail server for all mail you will want to deactivate the default MX record. To do this, click it from the list of DNS records.
As this is a system record, you are unable to delete it. However, you can click Deactivate record.
You will now see that the state of the MX record is inactive. If you ever need to activate it again simply return to it and click Activate record.
Changing the preference of the default MX record
The default MX record that is automatically created by the system has a preference of '10'. If you wish to change this then you will need to create a custom record with the same mail domain and mail exchanger entries, and the preference that you require. You can then deactivate the default record as above.
