* Choose `mailList` in `ObjectClasses` list, then click `Proceed`.
* Select `mail` as RDN, fill necessary values of attributes:
dn: mail=demolist@demo.iredmail.org,ou=Groups,domainName=demo.iredmail.org,o=domains,dc=iredmail,dc=org
accountStatus: active
cn: demolist
enabledService: mail
enabledService: deliver
enabledService: displayedInGlobalAddressBook
mail: demolist@demo.iredmail.org
objectClass: mailList
Now switch to `ou=Users` under you domain LDAP dn in left panel.
* Expand `ou=Users` in left panel.
* Find user account which you want to assign to new mail list we created above.
* Click user account in left panel.
* If attribute `memberOfGroup` exists in right panel:
* click `Add value` under it and fill mail address of our new mail list. For example: `demolist@demo.iredmail.org`
* Click `Update Object` to save settings.
* If attribute `memberOfGroup` doesn't exist in right panel:
* Click `Add new attribute` in right panel
* Choose `memberOfGroup` in drop-down list.
* Fill mail address of our new mail list.
* Click `Update Object` to save settings.
You can add as many `memberOfGroup=xxx` as you want, which means this user is assigned to many mail lists.
Here's sample to add external users as mail list members:
dn: memberOfGroup=demolist@demo.iredmail.org,ou=Externals,domainName=demo.iredmail.org,o=domains,dc=iredmail,dc=org
accountstatus: active
enabledservice: mail
enabledservice: deliver
mail: user01@external.com
mail: user02@external.com
memberofgroup: demolist@demo.iredmail.org
objectclass: mailExternalUser
