After digging through the code, I /think/ the problem is in libbalsa_mailbox_imap_fetch_structure() which loads only text/* and short messages completely (to be honest, I don't understand why multipart/* is working, though…). At least, the attached trivial patch, just loading single-part S/MIME messages just as text/*, solves the issue for me.
Thinking again about this issue, I guess this approach is not completely
correct. If all multipart/* messages are handled at some other place (are
they?), shouldn't *all* other top-level content types be loaded here? The vast
majority will (explicitly or implicitly) be text/*, and application/pkcs7-mime
is already somewhat special. But a message containing only a, say image/* or
application/pdf as the only payload is absolutely legal (although I saw the
latter with malspam attacks only…).
Thus, the more appropriate approach would be
