### Description

imap_createmailbox(IMAP\Connection `$imap`, string `$mailbox`): bool

Creates a new mailbox specified by `mailbox`.

### Parameters

`imap`

  An IMAP\Connection instance.

`mailbox`

  The mailbox name, see imap_open() for more information. Names containing international characters should be encoded by imap_utf7_encode()

  Warning

  Passing untrusted data to this parameter is insecure, unless imap.enable_insecure_rsh is disabled.

### Return Values

8.1.0 | The `imap` parameter expects an IMAP\Connection instance now; previously, a valid `imap` resource was expected.
