Why does Horde webmail take so long to open?

On startup, Horde/IMP checks every message in all folders, as well as the Inbox, against mail filter rules. This includes messages that have previously been checked against these rules. This can cause Horde/IMP to take a long time to display your Inbox.

Cruzio recommends that you use the filters in the Domain Control Panel instead of the filters in Horde/IMP webmail. See our domain spam filtering instructions.
