Inbox house keeping
The mail server is configured to prevent all your email staying in your inbox, this is to aid performance on the mail server. Typically the mail server will move email messages that have been sitting in your inbox to a folder called old-messages once they have been sitting in your inbox for 45 days or if there is more than 250 messages in your inbox. To configure these settings you need to login to the mailbox manager web service. You can access the mailbox manager web interface at http://mailboxes.mtheory.co.uk or securely at https://mailboxes.mtheory.co.uk.
Note if you login securely you will get a warning that “the identity of this website has not been verified,” or “server’s certificate does not match the URL,” or “server’s certificate is not trusted,” in your web browser. This is because the mailbox configuration service is hosted by our ISP, Dreamhost, and the certificate is issued by them rather than us. Your browser will normally let you view the certificate. If you click on this your browser will give you the option to always trust this certificate or install this certificate. Either of these should resolve this problem for you.
Once you login you will see a screen similar to that shown below. You can configure quite a lot of things from the mailbox manager interface. Many of these features are pretty self-explanatory but more details can be found in this post.
Under the heading Inbox Housekeeping you can change how many and how long messages are allowed to sit in your inbox. You can choose were to move messages to, whether the server should notify you via email that it has moved messages and whether or not you wish it to Even expire new messages, i.e. move messages which you’ve not yet read. Change the settings as you desire and then make sure you click on the button, Update Settings to save the changes.
