There is no way to forward emails to other email providers, there is no such possibility, nor is it a future plan.
At espiv we take the security and secrecy of communications very seriously, and we have implemented a series of features towards that direction and for the mail service that we provide, so we see no reason or usefulness in someone having an espiv email if the intend to forward it to somewhere else.
Generally, it isn’t a good practice to forward the emails that we receive to other servers, since, that way, we are sending data to a third person (especially when using commercial providers…).
Having an account at a provider that we trust is a basic step, but the way we ourselves use it is equally important.
