Help with Exim Certs

[Hybrice]

Hi guys, please can you help me out, here's the issues I'm having.

I've set up Vesta CP + added multiple domains.

server.hybrice.co.uk is my HOST

I've added
hybrice.co.uk
bdwills.co.uk
allabilitiesarchery.co.uk
yorkshireanimalshelter.org.uk

No matter what, every domain kicks errors back to me when connecting to email server stating "Certificate for server doesn't match address given"

I.E:
hybrice.co.uk doesnt match server.hybrice.co.uk
bdwills.co.uk doesnt match server.hybrice.co.uk
allabilitiesarchery.co.uk doesnt match server.hybrice.co.uk

it's like the host isn't allowing other domains to connect to it via mail.theirdomain.com and requires the all Email hosts to always be server.example.com, which is annoying as clients will have to use my domain as their email hostnames.

Any clues what I'm doing wrong?
