Sender Policy Framework(SPF)

Exchange 2007Leave a comment

Sender Policy Framework is basically used to over come spoofing of the emails. E-mail spoofing is a term used to describe fraudulent e-mail activity in which the sender address and other parts of the e-mail header are altered to appear as though the e-mail originated from a different source

Adding SPF record in the DNS will help to define from which IP address outgoing mail will be sent for the particular domain.  Any receiving domain will check all the receiving mails if it’s coming from the valid registered sender IP address.  If sender IP address is not registered or if spoofed by different machine then mail can be directly blocked as spam.

Unable to Download Mails in Entourage which has “+” in the subject

Entourage - Mac, Exchange 2007, Windows 2008Leave a comment

Unable to Download Mails in Entourage which has “+” in the subject line. Eg. Test + Mail

This happens on both Entourage 2004 and 2008 when you are running Exchange 2007  Sp1 on Windows 2008 Machine which has IIS 7.

To fix this, log into Exchange 2007 Mailbox servers and Client Access server and Mailbox Server and enter the below line in the command prompt. No need for restarting of machine is required.

%windir%\system32\inetsrv\appcmd set config “http://localhost/Exchange” -section:system.webServer/security/requestfiltering -allowDoubleEscaping:true /commit:apphost

You will see the following response after running the above command in the same window.

Applied configuration changes to section “system.webServer/security/requestFiltering” for “MACHINE/WEBROOT/APPHOST/Default Web Site/Exchange” at configuration commit path “MACHINE/WEBROOT/APPHOST”
