Courier (also known as Courier Email) was an email client for Microsoft Windows. The software was originally released in 1996 as Calypso by Micro Computer Systems (MCS). [1]
Courier supported the POP3, IMAP and SMTP protocols, provided several features for HTML security and allowed to use multiple e-mail accounts from one mailbox. Version 3.0 introduced html support and improved message security in comparison to version 2.0, however some features were not yet supported for html messages. [2]
In 1998 the MCS introduced another Calypso branded product, Calypso Message Center, intended for tracking and distributing messages for corporate customers. [3]
The company abandoned further development of Calypso, which was acquired in 2003 by RoseCitySoftware. [4] This led to freeware release of version 3.3 and name change of the next shareware version 3.5 to Courier. [5]
An upgrade path was negotiated with PocoSystems to add Courier-type features to Pocomail and direct Courier users to migrate to PocoMail 4.8 as a replacement for Courier 3.5. [6] Free versions of the unfinished beta, requiring no registration, were available at the Yahoo Courier user group. [7]
As of June 2021 the software is not available for download from official sources. [8]
Courier is no longer available for download from Rose City Software.
