SPAM segundo Dilbert

Um dos muitos feeds que leio é o Dilbert Daily Strip. Parece que o tema principal desta semana é o spam.

Não resisto a partilhar convosco as tiras de ontem e de hoje:

Exchange Server 2007 Mailbox Server Storage Cost Calculator

Ora aqui está mais uma grande ferramenta disponibilizada pela equipa do Microsoft Exchange: Exchange Server 2007 Mailbox Server Storage Cost Calculator.

Deixo-vos aqui um pequeno excerto tirado do post no blog You Had Me At EHLO:

In order to move forward with various designs like large mailboxes, IT departments need to understand one of the chief costs associated with Exchange mailbox servers, namely storage. To that end, the Exchange 2007 Mailbox Storage Cost Calculator is designed to help you determine a portion of the mailbox server cost, namely the disk cost (purchase price and lifecycle power and cooling costs). The calculator helps in two ways:

1. The calculator takes a series compares a series of storage design configurations and determines their respective costs. The underlying goal here is two-fold:
   1. To show that you can achieve the same capacity and I/O requirements utilizing Small Form Factor SAS disks for relatively the same cost as Large Form Factor FC disks.
   2. To show that there are other disk solutions (e.g., SATA) that can be viable and reduce the disk footprint cost.
2. In the situation where you are unsure whether you want to deploy Single Copy Clusters (SCC) or Cluster Continuous Replication (CCR), the calculator can compare SCC+SAN disk configurations against CCR+DAS disk configurations from a cost perspective.

Hopefully these measurements will show the value from a cost perspective in considering other disk designs, coupled with large mailboxes and continuous replication.

Windows Mobile 6.1 POP and IMAP Send Mail Patch

A Microsoft disponibilizou recentemente o Windows Mobile 6.1 POP and IMAP Send Mail Patch.

Overview
This behavior is associated with a feature that is introduced in Windows Mobile 6.1. The feature allows for mobile operators to specify an alternate SMTP server name that is used if e-mail messages cannot be sent by using the user-specified SMTP server name. If the mobile operator does not specify an alternate SMTP server name and if the Windows Mobile 6.1-based device does not connect, the e-mail account is corrupted and cannot send e-mail messages.

Exchange Hosted Services at Microsoft

Exchange Hosted Services at Microsoft é um whitepaper da colecção Microsoft IT Showcase que foi disponibilizado recentemente.

"The Microsoft Information Technology (Microsoft IT) group required a reliable and cost-efficient solution to increase protection against spam, viruses, and other messaging threats. Microsoft IT implemented Microsoft® Exchange Hosted Services to meet these needs."

A figura seguinte demonstra bem porque o spam é uma grande preocupação para a Microsoft:

"Spam submission attempts have increased at Microsoft over the past five years by more than a factor of 10 and almost tripled from 11 million to 28 million submission attempts in the fiscal year of 2007/2008, as indicated in Figure."
