It seems like it has been ages since this last happened - but Slashdot has a blurb about a real FOSS Story: Interview With Jeremy Howard of FastMail.fm. FastMail both runs and develops services based on Cyrus IMAP. Cyrus IMAP is Open Source, has an amazing depth of features, stunning performance, and is extremely standards compliant. It is very refreshing to see some attention given to a real Open Source solution that has been serving user for a decade. This in contrast to a not-open not-standards-compliant solution whose name you can probably guess - with whom Slashdotters appear to be utterly smitten [well beyond the point of clear thinking, but this is (a) Slashdot and (b) a normal side-effect of being smitten by something.] I'm a big fan of Cyrus IMAPd which has been very feature-rich and stable since at least 1999: you get delayed expunge, full text indexing, service-side filtering (SIEVE), shared folders, partitioning, replication, modification sequences, message expiration, and more. Other IMAP/POP servers are still trying to bolt these features onto themselves. If you aren't using Cyrus IMAPd I recommend you take a look, I honestly don't know why anyone would choose anything else.
