Not sure if at all related but earlier today (8+hrs ago) I had a disk fill up and then had to restart Zimbra to get items running. I also tried to run the reindex for an account.

Now my Zimbra server is running but my Defferred folder just holds messages and nothing is getting sent. Once I stop and start zimbra I get some mail but the rest keep staying in Defferred.

How can I check what is holding the mail up?

How can I force it through?
