No, it doesn't.  They increment, I strongly suspect, on a partially time
based counter, or possibly an account-wide number of deliveries based
counter, since one email in a group overnight gets around the same total
UID increment as the Linux kernel list in the same period, with some
hundred.

I have not yet taken the time to see if they available source code
explains why this is, or if it can be fixed, but the UID space is
*definitely* non-contiguous in Zimbra.

(Which, yes, does rather suck.)
