Do CA condo owners have a legal right to send email to individual HOA board members?

The president of our condo HOA has forbidden me to contact other HOA board members by email. He claims to be doing this on their behalf, but refuses to provide any evidence that he is authorized by them to do so. (He has been disingenuous and evasive on factual matters in the past). He has threatened me with fines if I persist. All of my emails deal with important HOA issues; I have contacted other board members because he refuses to answer questions. Can the president of an HOA board control communication with other members? Can I be fined for trying to communicate with them?
