I've just installed iRedMail, setup a new domain (atkins-solutions.com) logged in ok but i can't seem to be able to send / receive e-mails

Now i've created an 'A' Record called Mail that points to my External IP Address, then created an MX Record that points to my A Record so its saying mail.atkins-solutions.com is this correct or have i done it wrong?#

I've also added 2 TXT/SPF Records one for v=DKIM1 and the other v=spf1 ip4:[external ip] -all both with the hostnames of @ symbol

is this correct, do i need to do anything on the router, i've done port re-direction and pointed it to the internal ip address.
