Twisted Mail project provides client and server implementations of SMTP, POP3, and IMAP4.

These differentiate themselves from the Python standard library implementations both by presenting a much higher-level, easy-to-use interface and in their server components, which allow the implementation of custom servers for each protocol without dealing with protocol-level issues.

Twisted Mail includes a simple demonstration email server which accepts messages over SMTP, stores them in a Maildir arrangement, and can serve them to clients over POP3.

What's New in This Release:
The IMAP4 client now properly quotes usernames and passwords when necessary.
It also handles unsolicited FLAGS responses.
The IMAP4 server can now parse multiple literals in a single command and to FETCH requests with multiple BODY parts.
A bug where Deferreds returned from IMAP4 client methods would not receive connection lost notification has been fixed.
Startup time on OS X has been improved.
The SMTP server has been sped up.
The POP3 mailbox API has been expanded to allow Deferreds to be returned in some cases.
