The Tiger Envelopes email encryption project has released version 0.7.5. "IMAP is now supported, including IMAPS from Tiger's proxy to remote IMAPS servers. The installer and control panel now support mulitple mail clients. The control panel has much simpler key handling when you have more than one encryption package. A Thunderbird configuration bug that made it appear that your mail had disappeared was fixed. This can be resolved by restoring your preferences from the backup copy and reinstalling with this version."
