Everybody has his strengths and weaknesses – our strength is webhosting and our weakness is spam filtering. And we admit that. That's why we leave running mailservers to people doing that job better than we do. Our servers support sending mails, but we will not provide mailboxes at our server. If you want to use mail with your hosting, you need to find a mail service (e.g. Google Apps for your domain) and we will be happy to change your domain's MX records accordingly.
You probably mean our logfile rotation.
