We have a problem where emails we send are not recognised by the recipient's email client. This is because we are using the self-signed certificate created on the Options tab of Mail Security/Encryption.
We'd therefore like to use a trusted third-party certificate, ie one from a root that recognised by Outlook, Apple's Mail.app, Thunderbird, etc.
How can this be done in Astaro?
What sort of certificate do I need to buy? I don't want to have to create one for every email address.
Any recommendations re who sells such a certificate and what they call them?
Thanks,
James.
