70-284 Notes 6

• When performance monitor indicates that a server is experiencing a high level of paging activity = usually means there is not enough physical memory
  

  
   

• HTTP, NNTP, POP3, IMAP4, and SMTP virtual servers are available on an exchange server 2003 server
  
• POP3 and IMAP4 retrieve but do not send email. SMTP is used to send mail
  
• POP3 manages email on the client. IMAP4 manages it on the server
  
• HTTP virtual servers support WebDAV and OWA
  
• POP3 – TCP 110, POP3 SSL – TCP 995
  
• IMAP4 – TCP 119, IMAP4 SSL – TCP 993
  
• NNTP – TCP 119, NNTP SSL – TCP 563
  
• The default HTTP virtual server is configured using IIS manager rather than exchange system manager
  

  
   

• You can encrypt emails, including authentication information, if you obtain install, and associate a certificate
  
• You can control client access by IP number, subnet, or domain name
  

  
   

• To allow a user to send mail on your behalf, you can add them to your user account as a delegate
  

  
   

  
   

• Remote users need to download and install the S/MIME control to use digital signatures and encryption
  

  
   

• Although Unix users do not log on to any windows domain, they can have accounts in AD, and they can have exchange mailboxes
  
• Unix users can access their mailboxes by using the POP3 protocol as regular internet users do
  
• The winmail.dat attachment appears in all unix users incoming email messages because outlook users routinely send email messages in RTF format and the unix POP3 clients do not support it. To properly display the messages without affecting other users, configure POP3 settings on the 'Exchange features Tab' on the properties sheet for each unix users AD account
  

  
   

• Exchange server 2003 supports 2 types of policies: recipient policies and system policies. System Policies include mailbox store, public store and server policies.
  

  
   

• A DNS A record cannot be assigned a priority. You assign priority to the MX record. A lower priority number indicates higher preference
  

  
   

• ETRN (Extended Turn) is an extension to the Simple Mail Transfer Protocol that allows an SMTP server to send a request to another SMTP server to send any e-mail messages it has. The ETRN command has been specifically designed to allow integration with dial-up mail servers.
  

 

• To enable message tracking, you need to enable message tracking on all servers that the message will pass through
  

 

• To extract information from the recovered mailboxes in the recovery storage group and merge it with the new users mailboxes, you need to use the exmerge utility. You need to be assigned at least the 'Receive As' permissions for the mailbox store
  

  
   

• SMTP virtual server is the exchange component that routes email messages to their destinations. When an exchange user creates an email message, it is passed on to the default SMTP virtual server on the users home exchange server or to another SMTP virtual server in the organization. The SMTP virtual server analyzes the destination email address in the message and determines whether the recipient is internal or external. If the recipient is internal, the message is routed through the appropriate messaging infrastructure to the correct destination SMTP virtual server, which places the message in the recipients exchange mailbox. If the recipient is external, then the originating SMTP virtual server analyzes the existing messaging topology. If there is an SMTP connector that has an address space that matches the destination address in the message, the SMTP virtual server sends the message to the local bridgehead server, which handles the message in accordance with the routing configuration of the connector.
