### SOGo ActiveSync Configuration

Source: https://www.sogo.nu/files/docs/SOGoInstallationGuide

This section outlines the steps to enable Microsoft ActiveSync in SOGo, including package installation, Apache configuration, and a list of configurable parameters.

```APIDOC
## Enable Microsoft ActiveSync Support

### Description
SOGo supports the Microsoft ActiveSync protocol, allowing clients to synchronize contacts, emails, events, and tasks. It also supports Freebusy and GAL lookups, as well as 'Smart reply' and 'Smart forward' operations.

### Installation
To enable Microsoft ActiveSync support, install the required packages:

```bash
yum install sogo-activesync libwbxml
```

### Apache Configuration
Once installed, uncomment the following lines in your SOGo Apache configuration:

```apache
ProxyPass /Microsoft-Server-ActiveSync \
	http://127.0.0.1:20000/SOGo/Microsoft-Server-ActiveSync \
	retry=60 connectiontimeout=5 timeout=360
```

**Note:** Restart Apache after making these changes.

### Configuration Parameters
The following parameters can be adjusted to tune SOGo's ActiveSync behavior:

#### SOGoMaximumPingInterval
- **Type**: Integer
- **Description**: Maximum time in seconds SOGo will wait before replying to a Ping command. Defaults to `10` seconds.

#### SOGoMaximumSyncInterval
- **Type**: Integer
- **Description**: Maximum time in seconds SOGo will wait before replying to a Sync command. Defaults to `30` seconds.

#### SOGoInternalSyncInterval
- **Type**: Integer
- **Description**: Maximum time in seconds SOGo will wait before performing an internal check for data changes (add, delete, update). This value must be lower than `SOGoMaximumSyncInterval` and `SOGoMaximumPingInterval`. Defaults to `10` seconds.

#### SOGoMaximumSyncResponseSize
- **Type**: Integer (Kilobytes)
- **Description**: Overwrites the maximum response size during a Sync operation. A value of `512` means the response size will be 524288 bytes or less. Defaults to `0` (no overwrite).

#### SOGoMaximumSyncWindowSize
- **Type**: Integer
- **Description**: Overwrites the maximum number of items returned during a Sync operation. Defaults to `0` (no overwrite). Values greater than `512` may cause unexpected behavior with ActiveSync clients.

#### SOGoEASDebugEnabled
- **Type**: Boolean (YES/NO)
- **Description**: Enables logging of complete requests and responses for every EAS command. Defaults to `NO`.

#### SOGoMaximumPictureSize
- **Type**: Integer (Bytes)
- **Description**: Overwrites the maximum number of bytes returned for user pictures in EAS Search operations in the GAL. Defaults to `102400` bytes (100 KB).

#### SOGoEASSearchInBody
- **Type**: Boolean (YES/NO)
- **Description**: Enables EAS Search operations in all parts of a message. Defaults to `NO`, which searches only in Subject and From headers.

#### SOGoEASDisableUI
- **Type**: Boolean (YES/NO)
- **Description**: Disables EAS user interface options. Defaults to `NO`.

### Limitations

- **Outlook 2013/2016 GAL Search**: Does not search the GAL. Consider configuring Outlook to use a LDAP server.
- **Outlook 2013/2016 Multiple Address Books**: Does not seem to support multiple address books over ActiveSync.
- **Certificates**: Avoid self-signed certificates; they can cause intermittent Outlook issues.
- **ActiveSync Connections**: ActiveSync clients keep connections open, requiring sufficient `sogod` processes for many clients. Tune your SOGo server accordingly.
- **Repetitive Events**: Repetitive events with occurrence exceptions are not currently supported.
- **Outlook 2013/2016 Autodiscovery**: Not supported.
- **Outlook 2013/2016 Freebusy**: Supported via Internet Free/Busy feature. Requires `SOGoEnablePublicAccess` set to `YES` and a specific URL format: `http://<hostname>/SOGo/dav/public/%NAME%/freebusy.ifb`.
- **Large Mail Folders (IMAP)**: Adjust IMAP server settings (`imap_max_line_length` for Dovecot, `maxword` for Cyrus IMAP) to a buffer of 2MB if you have folders with thousands of messages.
- **Large Mail Folders (MariaDB/MySQL)**: Set `max_allowed_packet` to a large value (e.g., 64M or 128M) for EAS cache size with thousands of messages.
```

### SOGo EAS Push Configuration Examples

Source: https://www.sogo.nu/files/docs/SOGoInstallationGuide

These examples show how to configure SOGo parameters to support EAS push notifications effectively. They adjust WOWorkersCount, SOGoMaximumPingInterval, SOGoMaximumSyncInterval, and SOGoInternalSyncInterval based on the number of users and EAS devices. Key parameters like SOGoMaximumPingInterval and SOGoMaximumSyncInterval are set to 3540 seconds (59 minutes) to accommodate long-lived connections.

```ini
WOWorkersCount = 15;
SOGoMaximumPingInterval = 3540;
SOGoMaximumSyncInterval = 3540;
SOGoInternalSyncInterval = 30;
```

```ini
WOWorkersCount = 120;
SOGoMaximumPingInterval = 3540;
SOGoMaximumSyncInterval = 3540;
SOGoInternalSyncInterval = 60;
```

### Database Configuration

Source: https://www.sogo.nu/files/docs/SOGoInstallationGuide

This section details how to configure SOGo to use a PostgreSQL database, including setting up database users, schemas, and connection URLs.

```APIDOC
## Database Configuration

### Description
SOGo requires a relational database for storing appointments, tasks, contacts, and user preferences. This guide focuses on PostgreSQL but also supports MariaDB, MySQL, and Oracle.

### Database Setup Steps

1.  **Enable TCP/IP Connections for PostgreSQL**: Ensure your PostgreSQL server is configured to accept TCP/IP connections.
2.  **Configure `/etc/hosts` (Recommended Best Practice)**:
    To facilitate future database host migrations, it's recommended to add a local alias to your `/etc/hosts` file. This alias can then be used in `/etc/sogo/sogo.conf`.
    Example entry for a local database host:
    ```
    127.0.0.1	localhost db-alias
    ```
3.  **Create Database User and Schema**: Use the following commands as the `postgres` user:
    ```bash
    su - postgres
    createuser --no-superuser --no-createdb --no-createrole --encrypted --pwprompt sogo
    # Enter 'sogo' as the password when prompted
    createdb -O sogo sogo
    ```
4.  **Adjust Database Access Rights**: Modify the PostgreSQL access control file (`/var/lib/pgsql/data/pg_hba.conf`) by adding the following line at the beginning:
    ```
host	 sogo	 sogo	 127.0.0.1/32	 md5
    ```
5.  **Restart PostgreSQL Service**: Apply the changes by restarting the PostgreSQL database service.
6.  **Configure SOGo**: Update the SOGo configuration file (`/etc/sogo/sogo.conf`) with the database connection details.

### SOGo Configuration Parameters

SOGo uses several parameters in `sogo.conf` to define database connection URLs. Below are key parameters and their descriptions:

-   **SOGoProfileURL**: Sets the database URL for retrieving user profiles.
    *   PostgreSQL example: `postgresql://sogo:sogo@127.0.0.1:5432/sogo/sogo_user_profile`
    *   MariaDB/MySQL example: `mysql://sogo:sogo@127.0.0.1:3306/sogo/sogo_user_profile`

-   **OCSFolderInfoURL**: Sets the database URL for retrieving user folder locations (address books, calendars).
    *   PostgreSQL example: `postgresql://sogo:sogo@127.0.0.1:5432/sogo/sogo_folder_info`
    *   Oracle example: `oracle://sogo:sogo@127.0.0.1:1526/sogo/sogo_folder_info`

-   **OCSSessionsFolderURL**: Sets the database URL for storing and retrieving secured user session information.
    *   PostgreSQL example: `postgresql://sogo:sogo@127.0.0.1:5432/sogo/sogo_sessions_folder`

-   **OCSEMailAlarmsFolderURL**: Sets the database URL for email-based alarms (requires `SOGoEnableEMailAlarms = YES`).
    *   PostgreSQL example: `postgresql://sogo:sogo@127.0.0.1:5432/sogo/sogo_alarms_folder`

-   **SOGoEnableMailCleaning**: Enables cleaning of folders and mailboxes (removes mail older than X days). Default: `NO`.

-   **SOGoDisableOrganizerEventCheck**: Disables the organizer's calendar event check.

-   **OCSStoreURL**: Sets the database URL for storing all content data. Requires `OCSAclURL` and `OCSCacheFolderURL` to be set as well.
    *   PostgreSQL example: `postgresql://sogo:sogo@127.0.0.1:5432/sogo/sogo_store`

-   **OCSAclURL**: Sets the database URL for storing all Access Control List (ACL) data. Requires `OCSStoreURL` and `OCSCacheFolderURL` to be set as well.
    *   PostgreSQL example: `postgresql://sogo:sogo@127.0.0.1:5432/sogo/sogo_acl`

-   **OCSCacheFolderURL**: Sets the database URL for storing all cache data. Requires `OCSStoreURL` and `OCSAclURL` to be set as well.
    *   PostgreSQL example: `postgresql://sogo:sogo@127.0.0.1:5432/sogo/sogo_cache_folder`

### Example SOGo Configuration Snippet

```
SOGoProfileURL = "postgresql://sogo:sogo@db-alias:5432/sogo/sogo_user_profile";
OCSFolderInfoURL = "postgresql://sogo:sogo@db-alias:5432/sogo/sogo_folder_info";
OCSSessionsFolderURL = "postgresql://sogo:sogo@db-alias:5432/sogo/sogo_sessions_folder";
```
