An Open Look at Groupware

I recently posted on my other blog (in Portuguese) about the launching of the beta program for the Novell GroupWise 7, a competitor of Microsoft Exchange, as you probably know.

There are some topics I keep in my head, about which I plan to blog in the near future. The open source phenomenon and the alternatives to Microsoft Exchange is one of those subjects.

Today I found out a good article about this, An Open Look at Groupware, written by Jim Conley and part of the July issue of the Redmond Magazine. Jim talks about the 2 major open source Exchange competitors: and Open-Xchange. I particularly like the way he finishes the article:

For Exchange administrators considering any messaging or groupware upgrade or migration, open source groupware deserves a look. With Windows-based open source client alternatives to Outlook not yet fully baked, open source groupware will remain an unfeasible work in progress for some; others will find the possibilities of server-side groupware carry enough immediate benefit to replace an Exchange installation.

Of course, for me there’s no turning back. I’m completely addicted to Exchange!

Sender ID Framework SPF Record Wizard

This four-step wizard will guide you through the process of creating a new SPF record for your DNS domain.  You should add this DNS record to your domain’s DNS configuration.   Note that you may need to manually edit the SPF record created by this wizard if you want to use some of the more advance features of the SPF format.  For complete details please refer to the SPF record specification at

I discovered this while reading Gerod Serafin’s blog.

Uuups… I forgot to mention that the wizard is available here.
Meanwhile I found out that there is another wizard at this site.

Messaging Hygiene at Microsoft v2.0

The collection of documents “Messaging Hygiene at Microsoft” have been updated to version 2.0. These documents provide us a detailed description on how Microsoft IT manages the large quantities of spam and malware-infected messages in its inbound Internet e-mail traffic.

I haven’t had the time to read them yet, but a quick look unveiled that Sender ID is now mentioned.

The documents are available here.

Tech.Ed 2005 sessions available

The US Tech.Ed 2005 presentations are now online. I’m particularly interested in the track “Messaging and Collaboration” (what a surprise:-)), so I already started downloading PowerPoint presentations. Besides PowerPoint’s, you can also watch the recorded video of the sessions.

Meanwhile, I started the countdown to the European Tech.Ed 2005, where I’m going to work at the Ask The Experts (ATE) stand. This is new for me, so wish me luck.

[UPDATE 28-Jun]
Unfortunately this site is now closed (could it be that it was made available by mistake? Or maybe all was just a collective illusion.). If you try to access it, all you get is this message:

Please leave this area immediately. You are not authorized to access this site.

Meanwhile, the PowerPoints for the European Tech.Ed were supposed to be available yesterday, but they were postponed to Wednesday, 29-Jun.

ExBPA Version 2.1 is out!

Version 2.1 of the famous Exchange Best Practices Analyzer Tool (ExBPA) is now available for download.

I haven’t tried it yet, but Paul Flaherty have. According to him this new version adds performance checks:

When you select a Health/Performance Check, ExBPA will do the “normal ” health check, but it will then take 240 performance monitor samples every 30 second (So the whole scan will last over 2hours).
Once complete, it will then compare the samples it collected against the Troubleshooting Exchange Server 2003 Performance whitepaper and make recommendations.


Meanwhile, the site You Had Me At EHLO blogged about this:

Hotmail now has Sender ID

In its tradition of dog food consumption, Microsoft deployed Sender ID authentication in Hotmail, to protect e-mail users from malicious spam and scams. The tests started a few months ago, so this announcement was expected.

Sender ID will arrive to Exchange 2003 with the release of SP2, but meanwhile there are some 3rd-party products that already implement this technology in Exchange, such as GFI MailEssentials and SPF event sink.

Microsoft retires

The S*PAM _KiNgS site posted an article (also blogged by Donna and Bink), according to which Microsoft dropped the address Messages to that address will generate the following auto-reply:

Thank you for contacting Microsoft. Your e-mail will be handled by a Customer Service Representative within approximately 24 hours. Please note that the e-mail address you have contacted, “” will be retired on April 29, 2005. In the future, please visit to contact Microsoft.

The address abuse@domain is defined in RFC2142 and is intended for reporting inappropriate public behaviour (e.g., spam).
Just for curiosity, here’s a short list of (almost) all the addresses that should exist on every mail system:

MAILBOX     AREA               USAGE
———- —————- —————————
ABUSE Customer Relations Inappropriate public behaviour
NOC Network Operations Network infrastructure
SECURITY Network Security Security bulletins or queries

Configuring Exchange SMTP Gateways at Microsoft

Configuring Exchange SMTP Gateways at Microsoft is a new document available for download at the Microsoft site. It describes how Microsoft IT custom configures its SMTP servers to make its mail flow more securely and manageably.

Configuring a Simple Mail Transfer Protocol (SMTP) gateway to be secure as well as manageable can be a challenge. The e-mail team at Microsoft IT shares its experience with customers on configuring its Exchange Server 2003 SMTP gateways for optimal performance, security, and manageability.

Microsoft completes acquisition of Sybari

Microsoft Corp. today announced the completion of its acquisition of Sybari Software Inc. Originally announced Feb. 8, the acquisition of Sybari adds a critical security component to Microsoft’s efforts to help enterprise customers become more secure. As a wholly owned subsidiary of Microsoft, Sybari will continue to offer enterprise protection products for the Microsoft® Windows® platform.

The Sybari homepage has a new logo with the phrase “A Microsoft Subsidiary“. If we scroll down this page, we can see two other logos that are, under the current circumstances, at least curious:

Can a Microsoft Subsidiary be a Gold Partner?
Can a Microsoft Subsidiary be an IBM Partner?
