Upon trying to create an email account on any domain hosted on the server, I am receiving the following error:

First of all make sure that you have enough free diskspace on partition where /var directory located.

Thanks for the reply Igor, and sorry for the late response. I currently only have 27% diskspace used, so this should not be an issue.

There are a lot of errors like "No such file or directory". Seems there are removed necessary important files and directories. If you can't recover it by yourself - contact support team.
