Ilja, Have you checked out my patch since 2.0rc2 on SourceForge? I'd like to see this patch be the impetus for the 2.0rc3 release, as it adds much robustness that will need a few weeks of user testing to ensure that it is real-world ready.
Also, I got my Alpha out of storage and have found that the MD5 code does not segfault. Amusingly, the last time I compiled DBMail on this machine was 1.0rc3, when I wrote the authldap code :-) I have not yet tried a memory debugger to confirm that it isn't just working by mistake, though. Please let us know if you're waiting on 2.0rc3 until the MD5 issue is resolved; I'm sure that more people would suddenly be eager to learn MD5 hashing if a new or fixed implementation is what we need to continue towards a 2.0 release ;-) Aaron
