I too use Mail and SpamSieve – on Mavericks. Today I had the unnerving experience of seeing an email which I knew had two large PDFs attached, from a profesional address that has sent me dozens of similar emails, drop into my inbox and then disappear within a couple of seconds. It is nowhere to be found, neither the SpamSieve spam box nor the regular mail spam folder, not via a very thorough global search of the engtire computer and linked strorage. When I asked for the mail to be sent again, to a differne t email address coming into the same Mail installation, exactly the same thing happened. Thank heaven for WeTransfer.
I doubt very much that this is an "Apple problem" as it involves British Telecom; SpamSieve; Apple and dozens of other programs/factors etc. But it does happen; and I have seen it happen.
I don't represent SpamSieve, but I'm 99% sure that SpamSieve is not even capable of deleting messages. All SpamSieve can do is move messages from one location to another. So, if a message has literally disappeared, it's almost certainly not the fault of SpamSieve. :-)
Be sure to try Mail.app's search box (making sure it's searching "All" mailboxes), and also try a Spotlight search, for good measure.
Also, Apple has acknowledged issues with Mail.app in Mavericks (which may or may not be related to your issue, but is worth noting):
