Checking your Screenshots and your domain (theres no problem telling people about the domain ) you are using CloudFlare DNS.
You do NOT have a DNS entry for mail.domain.tld on CloudFlare (http://mxtoolbox.com/domain/mail.fdnsi.tk/)
Add a DNS entry for mail (either A record or CNAME, I'd add as A record) and you should be good to go.
You can't use Sentora DNS and CloudFlare at the same time, pick one (I would use CloudFlare as it is probably faster than your server)
