getmail is intended as a simple, secure, and reliable replacement for fetchmail. It retrieves email (either all messages, or only unread messages) from one or more POP3, SPDS, or IMAP4 servers (with or without SSL) for one or more email accounts, and reliably delivers into qmail-style Maildirs, mboxrd files, or through external MDAs (command deliveries) specified on a per-account basis. getmail also has excellent support for domain (multidrop) mailboxes, including delivering messages to different users or destinations based on the envelope recipient address.
python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. Mainly, it wraps the OpenLDAP 2.3+ libs for that purpose. Additionally, the package contains modules for other LDAP-related stuff (such as processing LDIF, LDAPURLs, and LDAPv3 schema).
Construct is a Python library for declaratively defined data structures, called "constructs". These constructs can both parse data into an object and build an object into data. Constructs handle fields of either byte or bit granularity, structs, unions, sequences, repeaters, adapters, validators, switching, pointers, on-demand (lazy) parsing, and many more. The library defines a large number of primitive constructs, as well a large inventory of file formats and network protocols.
mlmmjadmd is a networked server for administrating mlmmj. mlmmjadmd aims to make it easy to create responsive, synchronous user interfaces to mlmmj, unlike those currently in existence. mlmmjadmd currently supports all mlmmj functionality except access control. Additionally, mlmmjadmd includes a sample client implementation in PHP.
pyraknet is a Python extension that has bindings for the reliable UDP network library RakNet. pyraknet allows you to concentrate on your game or application rather then writing a your own networking code. It is straightforward to implement and you only need a small amount of TCP/IP networking knowledge.
IPy is a Python class and tools for handling IPv4 and IPv6 addresses and networks. The IP class provides comfortable parsing and handling for most notations in use for IPv4 and IPv6 addresses and networks. It was greatly inspired by the interface of the RIPE Perl module NET::IP, but it doesn't share the implementation. It doesn't share non-CIDR netmasks, so funky stuff like a netmask of 0xffffff0f can't be done here.
