I have set up postfix and am now attempting to set up dovecot. I did `apt-get install dovecot-common`
I have changed *dovcot.conf* to include the following

```
protocols = imap imaps

```

And I now get this error when restarting dovcot

> 
> Error: mail\_executable: Can't use /usr/lib/dovecot/imap: No such file
>  or directory Fatal: Invalid configuration in /etc/dovecot/dovecot.conf

Did I install the wrong package, is there another package I need, or am I missing something else ?

Thanks.
