SSL and hostname correct setup.

Hi there,
1) I have setup  centos web panel 7 on https://srv1.foodiebaba.in
Then It generates Self Signed 1 year SSL certificate , which shows error while browsing.
2) I also have my website https://foodiebaba.in for which I installed SSL from Auto SSL n working fine with it and its other sub domain.
3) But I am not able to set SSL trusted certificates for Hostname.
4) Cause due to this ftp and smtp are not working. Even I am able to configure and send mails from windows client. But php mail function is not working.
My DNS record are as follows
