## Chapter 41 Support for Apple Mail

Kerio MailServer supports some groupware features of IMAP and Entourage accounts in Apple Mail 10.4 and higher. The support enables to display events, contacts and task folders in the email client.

Cooperation of Kerio MailServer with Apple Mail is supported directly. This implies that it is not necessary to install any extensions to client stations. However, it is necessary to enable the support in the Kerio MailServer's configuration file:

1. Stop Kerio MailServer — before any manual edits in configuration files, it is necessary to stop Kerio MailServer Engine first.

2. In the directory where Kerio MailServer is installed, look up the `mailserver.cfg` file and open it.

   If the file is being edited on Mac OS X or Linux operating systems, login to the system as the root user (a special user with full access rights to the system).

3. Search the line including the `IMAPFullListing` value and rewrite the `0` digit with the `1` value.

4. Save the change and start Kerio MailServer.

Setting of the full support for IMAP in Kerio MailServer results in the situation where all users using IMAP to access their email share all types of folders and subfolders (email messages, calendars. contacts, tasks) in their email clients. However, these folders will be showed as email folders where any event, contact and task will be displayed as an email message with an attachment in the `.vcf` (contact) or `.ics` (event, task) format. For this reason, it is recommended to consider carefully whether the full support for IMAP in Kerio MailServer is really efficient.

For proper functionality of Apple Mail accounts, the following services must be running in Kerio MailServer:

- HTTP(S) — applied to Exchange accounts, if used.

- IMAP(S) — used both by IMAP and Exchange accounts.

- SMTP(S) — the protocol is used for email sending.

### Warning

In addition to configuration of the services on the server, it is also necessary to map corresponding ports on the firewall protecting the server. Otherwise, services will not be available from the Internet (for details, see section 2.3 Firewall configuration).

Specific options and settings in Apple Mail are focused in the Kerio MailServer 6, User's Guide).
