You're close.  I get this error on occasion too, for precisely the reasons you
mention.  /var is included in the snapshot process so every now and then there
will be files in Exim's outgoing spool which are quite transient.

However, rsync signals this issue with a different message saying that file X
has disappeared.

For these particular link_stat errors, the file/link path involved is the same
every time.
