Can I have Exchange Mailboxes and Non-Exchange Mailboxes on the same domain name?
When you purchase a Hosted Exchange Mailbox, you will be required to change the MX Record of your domain name from the standard Daily MX (mx.daily.co.uk) to the Exchange MX instead (emx.daily.co.uk).
This means that any existing mailboxes, email forwards or email announcement lists will stop working.
Generally speaking, customers should decide beforehand if they want the email functionality on any given domain name to either use Exchange services or standard POP email services (not both)
Frequently Asked Questions
Q. I really want to have Exchange Mailboxes and normal POP3 mailboxes on the same domain name. Is there any way around this?
A. Customers can leave the MX record as mx.daily.co.uk (instead of changing it to emx.daily.co.uk). This will allow customer's existing mailboxes and mail forwards to continue working as well as their Exchange mailbox(es).
However, this is not recommended as there may be problems when sending emails between the Exchange and Non-Exchange mailboxes on the same domain.
Q. What sort of problems could I experience?
A. If you do leave the MX record as that standard Daily MX, you may encounter delays when sending emails from your Exchange Mailbox to your Non-Exchange Mailboxes that are on the same domain name.
These delays are generally around 24 hours and your emails may also have a delay warning added to them
Q. Why is there this delay?
A. The delay is because you are bypassing the Exchange MX service and adding extra routing. This causes flags and warnings with the anti-spam settings and grey-listing policies, so while they will still be relayed, there will be a delay while they are filtered.
Q. ...but this is only an issue when sending mails between Exchange/Non-Exchange mailboxes on the same domain name? There would be no issues with sending email between different domain names?
A. Yes, this is correct. This may not be an issue for many users but if you have a large amount of email mailboxes on a particular domain (for instance, an office environment) then this may well pose a problem
Q. Is this just an issue with Daily?
A. No, not at all. You will find that many other Exchange providers do not allow you to order Exchange in the first place if you have active mailboxes already so have to cancel them first. Likewise, you will not be able to set-up any additional non-Exchange mailboxes on a domain already with Exchange.
At Daily, we want to allow customers the choice, providing they are responsible and aware of the limitations of not using the Exchange MX record.
