I am using a corporate mail account which is synchronized via IMAP to both my desktop client and my iPhone, which is exactly the way I like it. However, the account has a limited quota. With POP3 access, this was not a problem, as POP3 clients could be configured to remove messages from server after specified time. This option is missing from my Apple Mail IMAP account configuration pane. Is there a way to replicate this feature with an IMAP account, either on the client, or on the server side? If not, I will probably have to move old messages manually to some local folder on my Mac. Is there a method to retain a single-click searchability of both archived and current mail folders together?
