A Realtime Nexus é uma editora de livros online que disponibiliza as suas publicações mediante um registo grátis. Há já algum tempo que eu acompanho as publicações disponibilizadas e devo dizer que a qualidade é sempre de alto nível.
Decidi reunir aqui os links para os eBooks relevantes sobre o tema Messaging. Tal como vos disse, o download é gratuito, sendo apenas necessário um registo grátis.

The Administrator Shortcut Guide to Blocking Spam with Sender Validation (Alan Sugano) - Written by notable computing expert Alan Sugano, this guide will familiarize you with Sender Validation and how it compares with other anti-spam solutions (blacklists, key word filters, Heuristics and Bayesian filtering, etcetera). Since there are many different Sender Validation solutions to choose from, Alan will also help you discover what to look when choosing the right system for your business.
The Administrator Shortcut Guide to Email Protection (Paul Robichaux) - The Administrator Shortcut Guide to Email Protection will give you critical, need-to-know information to help you properly protect your corporate messaging system from a wide variety of external and internal security threats. Although the book focuses on Microsoft Exchange-based enterprises, the concepts, principles, and methodologies presented within are universally applicable to virtually all messaging platforms.
The Definitive Guide to Controlling Malware, Spyware, Phishing, and Spam (Dan Sullivan) - The Internet is home to malicious programs that can steal, destroy, and make data inaccessible; spyware that ignores social conventions of privacy to track Internet users' activities online; phishing scams that bring the art of the con artist to new threatening levels; and spam, the inevitable electronic counterpart to direct mail that requires so little investment even miniscule response rates justify its use. This guide explores some of the most pressing threats to businesses and organizations from the Internet along with best practices for addressing them.
The Definitive Guide to Exchange Disaster Recovery and Availability (Paul Robichaux) - Understanding Exchange disaster recovery can take a while. The first step, naturally enough, is to gain an understanding of the fundamentals of Exchange protection. Later chapters of this guide will describe the specific technologies you can use to improve the availability and recoverability of your messaging system and its related business services; first, though, we have to start with an explanation of the causes of downtime, the general classes of availability and protection technology, and ways to assess your Exchange environment to determine the most effective methods for you to better protect your Exchange infrastructure.
The Messaging and Web Security Essentials Series (Dan Sullivan) - The Messaging and Web Security Essentials Series is an online article series focused on helping security professionals address the ongoing task of keeping an organization secure from the multitude of online and messaging threats.
The Shortcut Guide to Exchange Server 2007 Storage Systems (Jim McBee) - The conventional way of planning for Exchange Server storage is to throw a lot of disk storage at the server and hope that is sufficient. Mail storage requirements continue to grow for even average users; these users place more and more capacity requirements not only on disk storage but also on disk I/O capacity. As current capacity requirements are exceeded, the storage system must provide scalability. The Shortcut Guide to Exchange Server 2007 Storage Systems, authored by Microsoft Exchange MVP Jim McBee, covers Exchange Server storage capacity requirement planning, the basics of using iSCSI SANs, and best practices for scalability and SAN operations.
The Tips and Tricks Guide to Secure Messaging (Jim McBee) - Threats against email systems have evolved to the point that protecting users, mail servers and bandwidth is no longer as simple as installing antivirus software. By some estimates, spam, phishing schemes, viruses, and other unwanted content now make up 70% of all email traffic into an organization's mail servers. The Tips and Tricks Guide to Secure Messaging by messaging expert Jim McBee introduces IT managers and messaging system administrators to the evolving threat landscape, emerging technologies for data protection, and best practices for protecting users, messaging system resources, and organizational data.

MVP Summit 2007

Ainda não tinha tido a oportunidade de escrever sobre o MVP Summit 2007, que ocorreu de 12 a 15 de Março em Redmond.
Do ponto de vista social foi mais uma vez um sucesso, dado que tive oportunidade de conhecer algumas pessoas com quem já me relacionava no mundo online (na foto, o Jorge Diaz do Chile, eu e o Anderson Patrício do Brasil, todos MVPs de Exchange Server).
Do ponto de vista técnico, as sessões foram muito boas, especialmente uma sessão de Q&A com o Brent da Microsoft, cujo conteúdo não posso divulgar, uma vez que estou sujeito a um NDA. Um dos tópicos bastante interessante foi sem dúvida a próxima versão do Exchange Server, nome de código Exchange 14 (é fácil perceber porque saltaram a 13).

Foi também bastante agradável a quantidade de posts que a Microsoft ou os seus colaboradores fizeram acerca deste Summit. Aqui ficam alguns exemplos:

Desta vez aproveitei a escala em Newark no regresso para dar um saltinho até à Big Apple. Olha eu aí com o Fellow MVP Alexandre Janeiro ;-)

E pronto, para o ano, em Abril, há mais (espero...).

TechDays 2007: a minha sessão

Ufff! Têm sido umas semanas complicadas, estas últimas. Na semana passada estive no MVP Summit, esta semana tenho estado no TechDays 2007. Hoje foi o dia em que apresentei a minha sessão: UCM007-Conformidade e Retenção de Informação no Exchange Server 2007 (espero dentro em breve disponibilizar os slides).
Durante a sessão, colocaram-me uma pergunta que não soube responder. O tema eram as Transport Rules e a adição automática de um disclaimer. Qual o comportamento com mensagens assinadas digitalmente?
Pois bem, após alguma pesquisa descobri que o Exchange Server suporta esta cenário particular. A forma como é ultrapassada a questão da não modificação da mensagem original é procedendo à sua re-envelopagem, enviando-a como um anexo. Mas esta é apenas uma opção de 3. As outras 2 passam por rejeitar ou ignorar a mensagem. Aqui fica um excerto do help file do exchange Server 2007:

Some messages, such as encrypted messages, prevent Exchange from modifying the content of the original message. Exchange enables you to control how your organization handles these messages. When you create a new disclaimer, you can decide whether to wrap a message that can't be modified in a message envelope that contains the disclaimer, reject the message if a disclaimer can't be added, or let the message continue without a disclaimer.
The following list shows each fallback action and its description:

Wrap If the disclaimer can't be inserted into the original message, Exchange encloses, or "wraps," the original message in a new message envelope. Then the disclaimer is inserted into the new message.
Important:
If an original message is wrapped in a new message envelope, subsequent transport rules are applied to the new message envelope, not to the original message. Therefore, you must configure transport rules with disclaimer actions that wrap original messages in a new message body after you configure other transport rules.
Note:
If the original message can't be wrapped in a new message envelope, the original message is not delivered. The sender of the message receives a non-delivery report (NDR) that explains why the message was not delivered.
Ignore If the disclaimer can't be inserted into the original message, Exchange lets the original message continue unmodified. No disclaimer is added.
Reject If the disclaimer can't be inserted into the original message, Exchange doesn't deliver the message. The sender of the message receives an NDR that explains why the message wasn't delivered.

Exchange Server 2007 Edge Transport and Messaging Protection

O MS IT Showcase tem novos conteúdos sobre o Exchange Server 2007. Este novo technical white paper - Exchange Server 2007 Edge Transport and Messaging Protection - descreve como a equipa de IT da Microsoft utilizou as novas funcionalidades do Edge Transport Server, em conjunto com o Forefront Security for Exchange Server, para prevenir a entrada de mensagens de malware.

In deploying the Exchange 2007 based messaging protection solution, Microsoft IT used all messaging protection features of the Edge Transport server role and Forefront Security for Exchange Server to block, delete, reject, or quarantine unwanted messages. To further increase security, servers were hardened and audited for vulnerabilities to ensure readiness for Internet visibility. The many steps that Microsoft IT took to design a network environment, combined with the messaging protection features of Exchange Server 2007, resulted in greater flexibility, fewer false positives, and reduced TCO.

Actualização de ferramentas para Exchange

Escrevi num post anterior sobre uma nova actualização da ferramenta Jetstress. Mas esta não foi a única ferramenta a receber uma actualização. Aqui fica uma lista das novas versões disponíveis no site da Microsoft:

Nova versão do Jetstress (v.08.01.0075)

Algum tempo depois de ter sido disponibilizada a nova versão do Jetstress (2007 ou 08.01.0038), a Microsoft disponibiliza uma actualização desta ferramenta de teste ao desempenho do sistema de storage.
A nova versão, v.08.01.0075, corrige alguns problemas, que estão descritos no blog do Hyungmin Lee: Jetstress 08.01.0075 has fixed a list of issues.
Aqui ficam os links para download das versões de 32-bit e 64-bit:

Overview
Use Jetstress to verify the performance and stability of a disk subsystem prior to putting an Exchange server into production. Jetstress helps verify disk performance by simulating Exchange disk Input/Output (I/O) load. Specifically, Jetstress simulates the Exchange database and log file loads produced by a specific number of users. You use Performance Monitor, Event Viewer, and ESEUTIL in conjunction with Jetstress to verify that your disk subsystem meets or exceeds the performance criteria you establish. After a successful completion of the Jetstress Disk Performance and Stress Tests in a non-production environment, you will have ensured that your Exchange disk subsystem is adequately sized (in terms of performance criteria you establish) for the user count and user profiles you have established. It is highly recommended that the Jetstress user read through the tool documentation before using the tool.

Note Jetstress is only supported when running with Exchange 2000, Exchange 2003, Exchange 2007 or newer versions of ESE.DLL. Also, due to this support limitation, Jetstress is only supported on Windows 2000 Server, Windows Server 2003, Advanced Server, Datacenter and newer Windows OS platforms (Windows NT 4.0 and older builds are not supported).
