Yeah those issues were found in the Qualys audit. They have been fixed so the codebase should only be stronger now.
I just wish we had something that wasn't written in C.

Try running any such program through Softbound + CETS or SAFEcode (already in LLVM). They turn C programs memory-safe. Should knock out most of your risk immediately with an acceptable performance hit unless your volume is really, really high. Code-Pointer Integrity at least protects control flow with max of around 10% penalty. Given they're all alpha by few developers, they need more people using them on various software and doing error reports if they fail.
PS. maybe that's one of the vulnerabilities mentioned in the report (1). Anyway it's an argument for me to run Qmail/qpsmtpd instead.
