I do believe it's an IO performance problem coupled with way too many messages in my own account. If I don't log in myself, everyone else's performance seems to be fine. I'm upgrading servers soon to fix the IO problem but I was hoping to learn about any tuning/optimization knobs for the meantime. - Grant ------------------------------------------------------------------------------ _______________________________________________ Courier-imap mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-imap
