An SMTP daemon that sits between the network and your actual SMTP server (it was designed with Postfix in mind but it should be possible to drop in front of other servers, like Qmail). It runs all SMTP traffic through an antivirus scanner (ClamAV by default) before passing it along to the rest of the SMTP server. Designed to be simple and lightweight (written in C instead of Perl).
Cuckoo is a system emulator written in Python for analyzing malware. It automates much of the process of reverse engineering malware samples, such as tracing execution, snapshotting memorry, tracing API and function calls, and dumping network traffic. Generates reports at the end of execution. Modular design, so it's easily customizable.
