     My question is : Can I have domains in relay_domains for which I check
    relay_recipient_maps and domains for which I don't check it?

     Example: -> My main domain, I know accounts in the primary MX -> I work as MX backup for it, I don't know their accounts

    relay_domains =,
    relay_recipient_maps = hash:/etc/postfix/valid_relay_accounts

     If I define N (let's say 100) accounts for in
    valid_relay_accounts and 0 accounts for, what would
    postfix do with with emails? Would postfix reject or
    accept it (no accounts defined in relay_recipient_maps por it).

     My problem is that I have knowledge of accounts of SOME of the domains
    I act as MXBackup for... and I want to "check rcpt to" only for those
    domains, while accepting any RCPT TO for the others.
