pyldaw is a Python wrapper for Local Delivery Agents (for
example, maildrop) under Postfix which allows an unlimited
number of extensions on a mail account with .qmail-like
functionality. For example, sending an email to user-ext1-
ext2-ext3@example.com could be processed by maildrop
running a filter called .mailfilter-ext1-ext2-ext3, or .mailfilter-
ext1-ext2, or .mailfilter-ext1, or .mailfilter, whichever is found
first.
