 | An SSL certificate is needed in order to use IMAP or POP3 over SSL/TLS.   |
 | No such certificate was found.                                            |

 | Please choose whether you want to create one now. This will then be a     |
 | self-signed certificate.                                                  |

 | If you choose not to create a certificate, please adapt Dovecot's         |
 | configuration file (/etc/dovecot/conf.d/10-ssl.conf).                     |

 | Create a self-signed SSL certificate?                                     |
