For the MX you can put johnny.heliohost.org as the mail server hostname.
For A and AAAA and records, please use the IPs shown in Plesk (refrain from posting them as it makes it easier for bots and attackers to scrape them from the forum), or you can perform a lookup on johnny.heliohost.org to get them.
You're right. I tested the reset password page, and it wasn't updating the SFTP password like it should. The password reset page has never reset the forum password though as the forum has it's own password reset function located at https://helionet.org/index/login/ and then click "Forgot your password?" We have discussed adding a checkbox to the https://heliohost.org/reset/ page so people can reset their forum password with one page. The reset page should set your SFTP password correctly now.
Please make sure the MX record for the orcagroup.top domain is pointed to us for email (MX set to johnny.heliohost.org), otherwise the domain and all subs will get disabled during domain cleanup.
I'll configure this shortly for you.
