The Ipswitch Collaboration Suite is an amalgam of four existing products, starting with IMail, the company’s Windows-based SMTP email server. To this is added an antivirus mail scanner, based on Symantec technology, and WorkgroupShare, which provides collaboration features for users of Microsoft Outlook. You also get instant messaging, but the mix isn’t a happy one, with a general lack of integration and a lot of rough edges to contend with. Ipswitch Collaboration Suite costs £12.32 (ex. VAT) per seat for a 100-user installation.
