===== How can I create a dynamic alias? =====

See [[:en:mail:create-like-alias]]

===== What happens if the condition for a dynamic alias also matches the name of another mailbox? =====

Say you have created the dynamic alias ''rob*'' on the mailbox ''bob@example.com'':

  Starting with rob

These addresses will all meet that condition:
  * ''%%rob@example.com%%''
  * ''%%robbie@example.com%%''
  * ''%%robert@example.com%%''
  * ''%%roberta@example.com%%''

So email sent to any of the addresses above will arrive in the mailbox ''%%bob@example.com%%''.

But what if the mailbox ''%%roberta@example.com%%'' exists too? 

If you create ''%%roberta@example.com%%'' as a mailbox and ''%%rob*@example.com%%'' as a dynamic alias on a different
mailbox, does email to ''%%roberta@example.com%%'' get sent to the ''roberta@'' mailbox, the ''bob@'' mailbox with the ''rob*'' dynamic alias, or both?

If you create a dynamic wildcard alias on a mailbox which matches
partially the name of another mailbox, **the email will be received on the alias mailbox only**.

This is because when a search is made from our mail service on a recipient, it stops at the first match: the alias(es).

This means if you create the same alias as the name of a different
mailbox, **you need to create the same alias on the other mailbox to continue to receive the mail**.

In our case above, we would simply need to add the alias ''roberta'' on the ''%%roberta@%%'' mailbox to ensure she receives her mail (and not Bob's).
