I tried to move a Zimbra install from an Ubuntu 8.04 to an Ubuntu 10.04 server, both running 7.0.0
Everything seemed to work fine, except now, email is just being queued.
I tried to requeue and email, and this is what I got:

How exactly did you do the migration?

The issue may have cropped up after I tried to use my SSL certificates, but I can't be sure.
I'll be running the migration again this weekend, with plenty of snapshot points I can roll back to.
