Corporate Email Clients Reviewed
An anonymous reader writes "Some companies seem to take the easy way out by depending solely on Microsoft for their email needs. To all IT managers who want to breathe easier, however, there are about eight alternatives in the market today, including Barca, Calypso, Eudora, Lotus Notes, Pegasus, Pine, The Bat and Mozilla Thunderbird--all featured in this review."
Both The Bat and PocoMail (the email component of Barca) have buggy and incomplete IMAP support, and the IMAP implementation in MS Outlook is prone to some really weird quirks that can render it unusable with certain IMAP servers. I haven't personally used Eudora or Pegasus, so I can't vouch for either of them, but Thunderbird and Pine both have excellent IMAP support.
However, despite being an excellent IMAP client, Thunderbird still lacks support for mail redirect, a basic feature of most mail clients and one that is frequently used in corporate environments.
