# 6.11 Ensure IMAP and POP server is not enabled (Not Scored)

## Profile Applicability

- Level 1

## Description

`Dovecot` is an open source IMAP and POP3 server for Linux based systems.

## Rationale

Unless POP3 and/or IMAP servers are to be provided to this server, it is recommended that the service be deleted to reduce the potential attack surface.

## Audit Procedure

### Using Command Line

Ensure no start conditions listed for `dovecot`:

```bash
initctl show-config dovecot dovecot
```

## Expected Result

No start conditions should be listed for dovecot.

## Remediation

### Using Command Line

Remove or comment out start lines in `/etc/init/dovecot.conf`:

```bash
sed -i 's/^start/#start/' /etc/init/dovecot.conf
```

## Default Value

Not installed by default on Ubuntu 12.04 LTS Server.
