POP3/IMAP Proxy Perdition mit MySQL backend

Perdition ist ein POP3/IMAP Proxy (SSL fähig) der zu mehreren Backend Servern (POP3 und IMAP) sich Verbinden kann. Die Entscheidung zu welchem Server er weiterverbinden soll erfolgt durch eine Tabelle. Perdition unterstützt mehrere Tabellenformate. Ich verwende MySQL.
