This time I will discuss how to create a mail server on Windows 2003 Server Operating System. As I will discuss later on the Create Mail Server by using the features, facilities and functions that are available in Windows 2003 Server, Mail Server installation, Configuration E-mail server and client configuration E-Mail using Outlook Express, and for the implementation I'm using Windows 2003 Server Enterprise Edition.The discussion begins with the workings of e-mail, the components involved (MUA, MTA, MDA), common protocols (SMTP, POP3, IMAP4), and a variety of mail servers in a Windows environment (ranging from actual Groupware Server with Proprietary Protocol to the Internet Mail Server is an RFC-compliant); until the reasons for selecting a specific product (in this case MDaemon). Here the discussion a bit wide to sample propietary Protocol and why it is not good (eg the "Recall Sent Mail", "For Your Eyes Only", and the case winmail.dat :-()
Next we discuss two examples of topology mail server, which is behind a Firewall Mail Server and Mail Server that deal directly with the Internet cloud: what the pros and cons of each of these topologies. Also about the design of the installation, where should we separate storage location for the Operating System, MDaemon, Mailbox, and log on separate drives (and if budget allows, use a SCSI disk).
We begin the installation and initial configuration, ranging from domain and DNS (here the workings of DNS also reviews more specific), delivery method (direct delivery or relay to a specific host or a combination of both, and what are the advantages / disadvantages of each way) , setting a timer, the number of session / thread (what is meant by SMTP Inbound / Outbound and POP Inbound / Outbound; following the determination of the number of sessions with relevance CPU utilization and bandwidth), Preprocessing, Archival (and a similar but alternative archival via Content Filter), Auto -pruning, and the Unknown Mail Delivery. Here we also discuss the concept of DomainPOP and MultiPOP in MDaemon.
Next we concentrate in the areas of security, ranging from what is the Open Relay and how to shut it down, DNS Blacklist, use spamfilter (following the example of the calculation of scores and learning Spam Assassin Spam / Ham), SMTP Authentication, tarpit, AntiVirus (Inline SMTP-time Virus Scanning In, different from ordinary AntiVirus AntiVirus for E-mail, normal risk for using AntiVirus on-access scanner on MDaemon folders, virus definition updates to the frequency and size of files that are not great). Here I also discuss the SPF and DKIM, as well as things that must be considered when implementation.
Because time is tight, I began to explain to the exclusion of the structure that had been prepared before the presentation. Finally, we discuss the implementation of the Content Filter, for example, to block the delivery of mailing lists (eg yahoogroups) and downstream bandwidth savings by receiving only one post yet spread to our internal server. Also about blocking a certain attachment to certain groups of people as well (eg Powerpoint attachment is only allowed to persons only). In addition, Bandwidth Throttling also discussed.
Unfortunately due to time constraints (already delayed one hour because so many things were discussed and fun discussion), eventually have to end at 10 pm. Though there are many things that have not been discussed, ranging from how to read / search logs, User Accounts, Mailing List, Gateway, WebAdmin, WorldClient, etc.. Finally we agreed to discuss further on the mailing list CEC-Smg@yahoogroups.com. My hope that this discussion brings positive benefits for colleagues who followed him.
