can courieresmtpd validate existence of mail addresses in the domains that are not local (listed in hosteddomains/locals)?
No.
oh :-(
We want to split SMTP servers from MX servers, and I'm curious if it wouldn't result to accepting recipients that don't exist and are reject by "550 user <...> unknown" messages.
We may distribute users' lists onto the SMTP servers of course, but we'd like to keep delivery on the MX servers.

This is typically done by exporting the user list as aliases: us...@domain.com: us...@server1.domain.com
All nonexistent addresses would therefore be rejected as unauthorized relaying.
What if the users have authenticated do they have relaying privileges?
Another question is - can courieresmtpd validate existence of addresses provided in mail from: in the same way as it validated rcpt to: ?
Nope.
:-(
Can you please answer my last question - can (are) domain in rcpt to: validated the same way as those in mail from:, when BOFHCHECKDNS is set? So the users wouldn't send mail to nonexistent domains...
