Your issue is that you are having your emails delivered to one entity while trying to retrieve them from another.

you should be aware that it is not advisable to use the domain name in the MX record unless you host it.  The reason being the IP assigned to it will be likely accessed in the browser when people do not want to type the www.burgessgalvin.ie but only use burgessgalvin.ie.
mail.burgessgalvin.ie

You need to decide:

1) Are you letting someone else host your email.
    Yes:
            a: This means you point the MX to their servers
            b: you access their servers to retrieve the messages
    No:
           a: you host your own servers
           b: use your own servers to retrieve the messages.
2) if you on the other hand have signed up for the HOST that will be listed in the MX record as a mail filtering provider i.e. they will handle the initial incoming email in-bulk and will then forward the emails back to your server after they have been "filtered," You should not include your own email servers on the MX record as that will defeat the purpose of the third party email filtering.

Use mxtoolbox.com to test list your domain's MX records and test SMTP on them. To show you that you have two separate entities handling your email. One is seemingly the host where your website is. and the other is internal.

Your current config is (in order of routecost):

burgessgalvin.ie.      14400      IN      MX      0 remote.burgessgalvin.ie.
burgessgalvin.ie.      14400      IN      MX      1 mail1.burgessgalvin.ie.
burgessgalvin.ie.      14400      IN      MX      2 burgessgalvin.ie.

remote.burgessgalvin.ie. 14400      IN      A      83.70.177.103
mail1.burgessgalvin.ie.      14400      IN      A      83.70.177.103
burgessgalvin.ie.      14400      IN      A      64.34.75.144

From a mailserver perspective this means;
- you can drop either mail1 or remote from the mx records as they are the same server
- mail delivered at 64.34.75.144 needs to be either pushed to the exchange server at 83.70.177.103 or the exchange server needs to request delivery from 64.34.75.144 in order to collect mail from that mailserver.
- Increase the routecosts to have some wiggle room so you can add a server before, between or after if such is needed (do so after the current change is all synced out).

Going back to the question with regards to the iphones not connecting to the exchange cluster; can it be that remote.burgessgalvin.ie used to point to a different ip address? If so then you are likely suffering from delayed dns caches either on the iphone itself (do a hard reboot of the iphone) or on the mobile telephony network; if the latter is the case then it's all a matter of waiting it out; no way to force it.
