Yes I do.
What I'd like to achieve is to have one common black and whitelist for a couple of domains which I host.

To be more specific.
I have about 15 domains.
4 of them is relaying to an exchange server of one of my clients.
Let's name them domain.com , domain.co.uk, domain2.com, domian2.co.uk.
Iredmail acts there as a spamfilter without recipent verification.
In can specify 4 different domains and everything is fine, however than client needs to modify each white and blacklist 4 times.

I wanted to set one domain to avoid this.
I've specified domain.com as domain and the rest as alias domains
I also want a domain to stays the same (no change like domain.co.uk->domain.com)

Thought that alias domain can handle it.

Hi @misieq,

Could you please help test this SQL query in /etc/postfix/mysql/relay_domains.cf? Replace old "query =" line by lines below. it works for me during testing.

query       = (SELECT domain
                 FROM domain
                WHERE domain='%s'
                      AND backupmx=1
                      AND active=1
                LIMIT 1)
                UNION
              (SELECT alias_domain.target_domain
                 FROM alias_domain, domain
                WHERE alias_domain.alias_domain='%s'
                      AND alias_domain.target_domain=domain.domain
                      AND domain.backupmx=1
                      AND domain.active=1
                LIMIT 1)

*) How did you test it?
