SSL mail problem

Hi,

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 https://pastebin.com/20Ek69jg

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