UKUUG, the UK's Unix & Open Systems User Group, is hosting their Spring Conference 2010 in Manchester, UK, from March 23rd through 25th.

First up, when you have a threaded mail box and don't feel like expanding the thread, Thunderbird shows you a "snippet"-preview of the thread in its preview pane (seen here on the right in Vertical View layout).

Perdition calls itself a mail retrieval proxy because it handles both IMAP and POP-3 clients (and their servers, of course) with or without SSL. From the documentation:
Perdition has many uses. Including, creating large mail systems where an end-user's mailbox may be stored on one of several hosts, integrating different mail systems together, migrating between different [...]
