How do I setup the free relay on CPanel
You must edit your settings in CPanel to avoid manual changes being changed by CPanel
In CPanel go to Main >> Service Configuration >> Exim Configuration Editor. Select Advanced Editor and find the textbox immediately below "Section: ROUTERSTART" then insert the following text into the textbox:
smarthost:
driver = manualroute
domains = ! +local_domains
transport = remote_smtp
route_data = "relay.redstationmail.co.uk"
Can I send mails from other servers?
Free e-mails are provided for use by your Redstation dedicated server only. You are not permitted to use this service for relaying from other providers. Packages can be provided from as little as £29
per month for 1000 mails per day to send from anywhere.
