There are 2 things you can do before your move to make things easier on the day.
If your domain is managed through us we have already changed the nameservers for you.
Resellers: Please reglue your private nameservers to these IPs. You can keep your own private nameservers, just change the IP record associated with them via your client area.
To improve security, SSL will be mandatory for all mail connections.
Please enable this in your email client as soon as possible.
Enter your domain below to check where your nameservers are pointing:
Yes, a number of changes will be needed in some cases. Broadly these are:
Full specific details on each of the above steps are detailed in your migration email.
Yes, a small window of downtime is expected, we anticipate this to be between 06:00 and 08:00 BST on your upgrade date.
By default, STRIKE which is the anti spam for inbound mail uses the A record of the domain as it's route for directing mail traffic. In these cases, all of the A records were not pointing to Smart's servers as they would be by default, therefore the mail was trying to direct traffic to the A record that was simply rejecting it.
These domains needed to be logged into to change the 'Route' in which the mail directs traffic as the A record isn't a Smart based A record.
To fix this, for the respective domain, you'd need to login to their cPanel and head to the 'Professional Spam Filter' under 'EMAIL'. Select that and then select the respective domain and click 'Login' to the right.
Once logged in, head to 'Edit Route(s) on the left sidebar and adjust the route to be that of the hostname of the server. In this case it was SERVERHOSTNAMEHERE. Input that and remove the previous route (that pointing to the main domain name, which in turn points to the A record hosted elsewhere).
Once complete, save and then head to the 'Clear callout cache' on the left sidebar and clear the cache. Mail will then begin routing correctly and working as normal.
If you are using any of our existing nameservers (which end in either .mycpanelcloud.co.uk or .smarthosting.co.uk), then you will need to change them to our new ones before the upgrade:
Note: If your DNS isn't hosted by us, you will need to update the IP address in your zone file. You can use the table above and in your client area to find your old and new IP addresses. Further details on updating external DNS services will be included in your specific upgrade email when this is sent. It is critical that the IP address is changed as close to the upgrade as possible, else your site will still be pointing to old hardware.
"We've been absolutely delighted with Smart Host from the very start. When I say it's like getting a Rolls Royce for the price of an old Cortina, I mean it! The price is great but the customer support is Rolls Royce standard..."
"Finding a good, reliable and most importantly approachable reseller provider has proven hard for my business over the past few years. I have moved from 4 hosting providers mainly due to downtime and poor support. I don’t normally write reviews however after joining smart last year I am extremely impressed not only with the speed of there support but also the speed of there platform. The team are friendly and on hand to assist above and beyond the call of duty every time..."
"I don't often write reviews online, but I feel credit ought to be given where it's due. Since discovering Smart Hosting, I have found their diverse array of features and generous resource offering to be superlative to any hosting provider I've ever come across before. I'd particularly like to thank James from the support team for going above and beyond his duties and offering patient and diligent customer support with blazing fast response times..."
