SSL mail problem


I have problem with setting up mail ssl (im using 30 day trial ssl)
I think the problem is hostname or dns record.
My hostname is server1.domain.tld ssl was signed for domain.tld (not wildcard)
So i should buy ssl for mail.domain.tld and set this record on all mx record hosted domains?

log from checktls

And another problem with ssl i have 2 websites with ssl and when i add this 30 day trial ssl for im redirecting to one of this 2 websites that have ssl.
