Natural sounding sentences in English usually do not begin with prepositional phrases like *from whom, * except maybe in a question, and usually a formal question.
- From whom do you receive money, Mr. Kim?
- Is it important for you to know whom you receive it from?
- Whom, in fact, do you receive it from?
Right, so the above is formal. People actually say who here and it's fine in spoken English:
Who, in fact, do you receive it from?
Answer: Who I receive money from is important to me. OR Whom I receive money from is important.
Generally, therefore, we would start the sentence with who or whom and not from whom in a declarative sentence (not a question).
It is true that the verb receive takes from but it is usually placed at the end and separately from the who or whom.
There is no need for a that. That introduces a relative clause:
- The money that I receive from my family is always in cash.
