Rudi LDA

This is a local mail delivery agent (LDA) that I use for sorting/processing my incoming e-mail. The LDA sits between chasquid and my Maildir directory, which is then served by Dovecot. Notably, the whole idea here is to not use Dovecot's LDA or LMTP at all, since I want to write my own code to process my e-mail and executing external scripts from within Dovecot using Sieve just sucks.
