nshi/pymailheaders

Pymailheaders is a small GTK+ program which displays the senders and the subjects of your E-mails. It was innovated by xmailheaders, with a few more handy features like new mail highlighting, multi-language support, lauching regardless of network connection status and auto-reconnecting. Pymailheaders was written from scratch in Python for portability and easiness reasons. IMAP4, POP3 protocols and XML feeds are supported now.
