I need to match all messages sent from some specific domain and all its sub-domains.

I prefer using regular expressions for this kind of tests:

if address :regex "From" "[@.]example\.(com|org)$" {...}

This will match all addresses for example.com, example.org and their respective subdomains.

Or in readable sieve:

if anyof ( address :domain :is "From" "example.org", address :domain :contains "From" ".example.org" ) { keep; }

Which might match "subdomain.example.org.gotcha.com", but how often would that happen?

Kind regards,
