What an alias domain is used for?

Let's say you have a mail domain example.com hosted on your iRedMail server, if you add domain name domain.ltd as an alias domain of example.com, all emails sent to username@domain.ltd will be delivered to user username@example.com's mailbox.

• Find the LDAP object of your mail domain which you want to add alias domain in left panel of phpLDAPadmin, click the ldap object, phpLDAPadmin will show detailed LDAP attributes/values of this domain in right panel.

• Add a new LDAP attribute domainAliasName to this domain account, set value to the alias domain (e.g. alias.com).

• Make sure LDAP attribute enabledService has value domainalias, if not, add it manually. Note: enabledService has few values by default.

Now you should add additional mail address for all mail users, lists, aliases. For example, if you have mail user user@example.com, you should add additional email address user@alias.com for this user. Steps:

• Add a new LDAP attribute shadowAddress to this mail account, set value to user@alias.com. WARNING: You must user the same username part as original email address.

• Save your change.

If you have several mail accounts (mail users, lists, aliases), you have to add additional email address for them all.
