Client can't connect to email client using SSL?

Hi all,

We've just moved from an old server to a new one (latest software) & i'm having an issue with a couple of clients not being able to setup their e-mail accounts properly in Outlook & Apple Mail.

When setting up there accounts in outlook it says first of all "An encrypted connection to your mail server is not available.." and will only let them set it up if you manually enter the hostname of the server (as their domain is not currently hosted with me, they are just pointing there mx records to me. Webmail on the server works fine.

I've done a bit of digging but can't seem to remedy the problem. I have a valid SSL on the hostname and have installed that on the main 4 services.

Would anyone be able to shed a bit of light on this?

 

Thanks for that - that seems to have made them able to connect through Outlook & iPhone mail, but they are using Apple Mail on their desktop. Whatever I do I cannot seem to get Apple Mail to connect to it - says unable top verify account name or password.

 

Hi, thanks for your help. I don't think the issue is to do with the server, it sets up in Microsoft Outlook, iPhone etc with no issues at all. Just looking to see if theres any current bugs with El Capitan Apple Mail
