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?
domain1.com -> My main domain, I know accounts in the primary MX
customer.com -> I work as MX backup for it, I don't know their accounts
relay_domains = domain1.com, customer.com
relay_recipient_maps = hash:/etc/postfix/valid_relay_accounts
If I define N (let's say 100) accounts for @domain1.com in
valid_relay_accounts and 0 accounts for @customer.com, what would
postfix do with with @customer.com 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.
