How to enable catch-all email in iRedMail Open Source edition?

Question

How to create catch-all email alias for domain in iRedMail Open Source edition?

I know that's possible via LDAP and found the following instructions: http://iredmail.org/wiki/index.php?title=Addition/OpenLDAP/Catch-all

The problem is how exactly to add this parameters via phpLDAPAdmin?

I select "Create new entry here" and choose mailUser type.

Then in step 2 first question is about "RDN" with select box "select RDN attribute".

What should I choose as RDN? Which fields of the "Create Object" form should be filled?

Unfortunetly there is completely no validation of user input and final errors does not contain explanation what's wrong

Also when I try to import example from iredmail wiki phpldapadmin it gives LDIF Import Parse Error Description: A valid dn line is required []

dn line is: dn: [email protected],ou=Users,domainName=mydomain.eu,o=domains,dc=myserver,dc=pl

Answer 1

Using the example at the web page given, use a known good tool like ldapmodify to add the user:

ldapmodify -D admin-dn -w admin-dn-password <<!
dn: [email protected],ou=Users,domainName=a.cn,o=domains,dc=iredmail,dc=org
changetype: add
accountstatus: active
cn: catch-all
mail: @a.cn
mailForwardingAddress: [email protected]
mailForwardingAddress: [email protected]
objectclass: inetOrgPerson
objectclass: mailUser
sn: catch-all
uid: catch-all
!

Answer 2

Full working version, only need to change domains and passwords:

ldapmodify -D cn=Manager,dc=yourdomain,dc=com -w your-admin-password <<!
dn: [email protected],ou=Users,domainName=a.cn,o=domains,dc=iredmail,dc=org
changetype: add
accountstatus: active
cn: catch-all
mail: @a.cn
mailForwardingAddress: [email protected]
mailForwardingAddress: [email protected]
objectclass: inetOrgPerson
objectclass: mailUser
sn: catch-all
uid: catch-all
