LDAP: Add per-domain catch-all account

With default setting, iRedMail will reject emails sent to non-existing mail accounts under hosted mail domains. If you want to accept these emails, you need a per-domain catch-all account.

With OpenLDAP backend, you can add an catch-all account for mail domain example.com like below:

dn: mail=@example.com,ou=Users,domainName=example.com,o=domains,dc=iredmail,dc=org
accountstatus: active
cn: catch-all
mail: @example.com
mailForwardingAddress: user_1@example.com
mailForwardingAddress: user_2@example.com
objectclass: inetOrgPerson
objectclass: mailUser
sn: catch-all
uid: catch-all

With above catch-all account, emails sent to non-existing addresses will be forwarded to both user_1@example.com and user_2@example.com.

NOTES:

Address user_1@example.com and user_2@example.com must exist.
With iRedAdmin-Pro, you can manage catch-all account in domain profile directly. Screenshot attached.
