Comcast Goes to Zimbra

tenchiken writes "Zimbra, an Open Source enterprise messaging app, just scored a major win. Comcast will be moving mail services to Zimbra for all of their customers. Zimbra has been picking up steam for a while now, and appears to really be challenging Microsoft in a area that Exchange has been dominated in. Add in support for Samba Domain Controllers and Linux Authentication, Offline Access and Evolution Support and we might finally have our long desired Open Source Exchange killer."

    I'd have to presume that Exchange wasn't what Comcast is moving from.
    This is correct, they were on another large hosted solution.

    None of that has anything to do with what Exchange is aimed for. Exchange is not used for any major ISP that I'm aware of (not even Microsoft's public email services), nor should it be. Exchange is built to integrate with Domain Services. It's made so that you can have resource scheduling integrated with calendars and busy notification. It's made so that a secretary can log into her boss's account and check all his emails and send emails as herself or under his name as if he sent them himself. It's made so that when the idiot sends out the video of the latest commercial he thinks is cute that there is only one copy of the video on the server, and the emails point to it, rather than replicating it 1000 times.
    While your statements about Exchange may be correct, your (implied) statements about Zimbra are not.
    • Resource scheduling, integrated in calendar with busy notification - Zimbra has that.
    • Delegated accounts (secretary/boss) - Zimbra has that, for email and calendar.
    • Single instance store (1000 copies sent, one copy on disk) - Zimbra has that
    I'm not claiming that Comcast is planning to OFFER all of these features - but they certainly exist in Zimbra.
  24. Not an Exchange killer yet by Anonymous Coward · · Score: 0

    The *REAL* Exchange killer will be CalDAV. Yet another proprietary calendaring/scheduling back end from Zimbra means competing with MS on their turf - and we all know how that always turns out. But when F/OSS apps implement open standards, they kick ass. Think HTTP/HTML - Apache. Think SMTP/POP/IMAP - Sendmail, Postfix, Cyrus, etc. These are the most important protocols and applications around. It's time to do the same with calendaring.

    Proprietary calendaring solutions only extend as far as your local implementation. I want to coordinate my schedule with more people than that. I want my coordinate my calendar with my family, with my friends, with my vendors, with my collegues at other institutions, with local town events, with my kid's school - NOT just my co-workers. I don't want to care if they use webmail, crackberries, or whatever. This requires open standards. The standards exist. They are pretty new. Now we just need good reference implementations. If Zimbra does this, I predict they will own the market.

    Bedework already supports CalDAV. Bedework/Sakai integration is taking place. Lightning and Sunbird work on top of CalDAV. CalDAV is happening. So Zimbra: please please please get on CalDAV, so we don't have to continue suffering the interminable curse of incompatible proprietary calendering protocols. As we've seen, when open standards take off, even Microsoft has to play along. It's time.

    Zimbra really seems to want to be the only thing on a machine though. I've reverted to Mail.app and UW-IMAP until I get the gumption to build a machine just for Zimbra.

    I'd agree that it's Enterprise Ready, having seen a couple admin friends roll it out to their enterprise, seems pretty sweet. Their licensing model looks pretty sane too. Full functionality in the OSS version, then pay extra for all the Exchange/Outlook integration features, hopefully that brings in enough cash to keep development going for all us folks that don't need those plugins.

      "Another system" would be another application that the user has already authenticated to - an employee portal, for instance. "preauth keys" are basically an encrypted session key that tells zimbra that a trusted application has authenticated the user and can vouch for their identity.

      "Preauth" is a hook that will allow Zimbra to share authentication with pretty much anything. It's an API so it can be as secure (or insecure) as you like.

      Preauth keys allow any web based service to redirect with authentication into the Zimbra server. You can use any LDAP server that implements the standard classes for authentication as well.
