    Mark Crispin, father of IMAP, RIP

    Mark Crispin, father of the Internet Message Access Protocol (IMAP) died on December 28, 2012. Due to the contribution Crispin made to email interoperability and access, his passing deserves the acknowledgement of the global email community. Although it’s now regarded to be an outdated protocol because it does not support the advanced features of modern email systems, IMAP still has a dedicated band of followers and is used by tens of millions of people daily to fetch email from Gmail, Exchange, Zimbra, and just about every other email server on the face of the planet. The major value of IMAP is its sheer ubiquity, with the golden rule being that if a client can’t access a server using another method, it probably can using IMAP. The world of email was very different when the first versions of IMAP were written at Stanford University in the mid-1980s. The vast majority of mailboxes were served by proprietary systems such as Digital’s ALL-IN-1 or IBM PROFS and the Internet was a loose collection of servers connected with dial-up telephone links. The Post Office Protocol (POP) existed then as it still lingers on today, but only allowed users to download messages from a server. This sufficed in many situations then – servers and clients alike were resource poor and it was deemed to be a good thing to remove items from server mailboxes to bring them down to clients for processing. Crispin conceived IMAP as a mail access protocol that advanced the state of the art by allowing access to more than an Inbox folder on the server, supported concurrent access to mailboxes, and offered much more functionality to manipulate messages than the POP protocol allowed. Originally developed in Lisp, a language much favoured by people working on Artificial Intelligence at the time, on a Digital TOPS-20 computer, the value of IMAP was realized in its fast evolution and adoption to the point where IMAP4 appeared in 1994. IMAP4 has been extended many times with additions by vendors (...More

    For many companies, 2013 is likely to be a year of system upgrades, or at least investigating the new versions of software as they become available. In a Microsoft-centric world, businesses have big decisions around nearly every major IT component, from OSs with the releases of Windows 8 and Windows Server 2012, to office productivity with Office 2013 and SharePoint 2013, to administration with System Center 2012. Unless your Microsoft Exchange Server implementation is seriously ailing, moving to Exchange Server 2013 might be a low priority this year. Even if your business does need a messaging system upgrade, either to get off older, no-longer-supported software or to take advantage of new features, installing the new Exchange still might not be in the budget....More
