There are lots of API changes in gmime 2.6 crypto handling. By adding preprocessor directives, it is however possible to add gmime 2.6 compatibility while preserving compatibility with gmime 2.4 too. This is mostly based on id:"8762i8hrb9.fsf@bookbinder.fernseed.info". This was tested against both gmime 2.6.4 and 2.4.31. With gmime 2.4.31, the crypto tests all work fine (as expected). With gmime 2.6.4, one crypto test is currently broken (signature verification with signer key unavailable), most likely because of a bug in gmime which will hopefully be fixed in a future version.
