Features

1. Runs stand-alone.
2. Less than 2200 LOC:
   • very small and compact, easy to modify
   • statistically seen, less bugs than other software with the same functionality
3. IPv6 ready (currently untested)
4. No root exploits possible: the server only runs as root during authentication and the authentica tion routines are designed to be secure.
5. All temporary files are created securely.
6. Allows POP3-over-SSL (based on OpenSSL): secure POP3 sessions are possible through this feature, which is supported by most of the common MUAs.
