If I understand correctly, DER encoding should not be the problem, since DER/BER allows encoding of arbitrarily sized contents. There isn't a limit on length - well, there is, the content must be shorter than 2^(8*126)  - 1, i.e., 2^1008 - 1 bytes, inclusive. 
I believe "excessively large" does not imply such messages/attachments.
