  • System Requirements -- this web-based component is designed for use with DAWKCo POP3 Server Hosting Version and requires the following system configuration(s).


    • Pentium Class Processor(s) (I / II / III / IV), or compatible
    • Windows® 2000 Server Operating System
    • Network Interface Card (or equivalent) and TCP/IP Protocol
    • Fixed Disk with NTFS File System Format
    • IIS (Internet Information Services) v5.0 with a World Wide Web Publishing Service default website
    • DAWKCoTM POP3 Server Hosting Version 5.0 (or later)


    The web pages output from the utility should work well with any Internet Standards based web browser, regardless of operating system, that conforms to the following W3C (World-Wide Web Consortium) standards:

    • HTML 4 (Hyper-Text Markup Language)
    • CSS 2 (Cascading Style Sheets)
    • ECMA 2.62 Scripting (European Computer Manufacturers Association), a.k.a. JavaScript, or JScript

    That includes current web browser versions from Microsoft®, Netscape® and Qualcomm®, and online services such as AOL®, CompuServe®, MSN®, Prodigy® and others.

    Password Inputs Note: with some web browsers, including Netscape Navigator v6, you must not "copy & paste" values into web form Password inputs. If you do, invalid input will be generated. Therefore, if you are using such a browser, you must type your password entries.

  • POP3 Synchronization -- full synchronization between the POP3 Server Service, the MailDaemon e-Mail Routing Service, the WebMAIL Extension for IIS, the stand-alone executable POP3 Admin Utility, and the web-based POP3 Domains Admin and POP3 Password Changer Utilities is provided by the software.
    Specifically, simultaneous configuration updates being performed by different parties that might cause conflicts or collisions are blocked in a FIFO (First-In-First-Out) queue fashion by using system global named Mutex (Mutual Exclusion) and Event synchronization objects and Interlocked Variables. While this method should prevent crashes and/or data corruption due to collisions during configuration write operations, it presents the possibility of time delays and/or time-outs during a wait for ownership of an object.
    All of the DAWKCo mail services and utilities (including web-based) will use a default synchronization wait time-out value of 60 seconds, unless you override that value by setting Windows System Registry key values. See the "POP3 Synchronization" section of the setup help file for the web-based POP3 Domains Admin Utility for details about overriding the "Sync Wait Timeout" value.
    Note: if a web-based admin operation times out, it's most likely that Mutex ownership for an object could not be obtained due to a sharing conflict. If you get a "cannot find server, or DNS error" message from the web browser, then it's likely that the web-based admin context initialization failed because the default website was being restarted during a global update by the stand-alone executable POP3Admin Utility. In either case, just try again.

  • Security Considerations -- in order for the DAWKCo WebMAIL process to properly authenticate and impersonate users, using the same techniques used by the DAWKCo POP3 Server for Windows Logon authentication and impersonation, the IWAM_machine "Launch IIS Process Account" User account must be granted the TCB (Trusted Computer Base) privilege. The privilege is required by the operating system for any process that performs Windows Logon functions. (According to Microsoft, that requirement will be eliminated in the next version of Windows server operating system ("Whistler".) To minimize any potential security risk, the DAWKCo WebMAIL process is isolated from the IIS process, and the process security context is immediately switched from that of the IWAM_machine account to the account controlling access to the logged on POP3 client's mailbox. Additional security measures have also been introduced, for example, stronger encryption of Windows Usernames and Passwords in a form that is different from that used by the POP3 Server, as well as other data obscuring techniques. In any event, even if a hacker were to hack a POP3 Alias/Password combination, a client's mailbox is as far as they would get.

  • Client Usage -- Complete Help documentation on all features and use of the utility is provided via help links on the utility's web pages. Clients access the web-based POP3 Password Change Utility at the following location:
    Where <default_website_domain> is replaced with the domain name, or virtual domain name, for your IIS web server default website.
    • e-Mail Alias/Address -- you must enter your full e-mail address here, with one exception. If your mailbox is in the same default local domain, or FQDN (Fully Qualified Domain Name), as the mail server, then you may enter just your POP3 e-mail alias. The POP3 e-mail alias is the username part that comes before the '@' symbol in your e-mail address. For example, if the FQDN of the host machine that is running the POP3 Server is pop.company.com and your e-mail address is alias@pop.company.com, then you may just enter alias for this input. If, however, your e-mail address is alias@company.com, then you must enter the full e-mail address.
    • Old e-Mail/POP3 Password -- enter your old, i.e., existing, POP3 Password here. Your POP3 Password is the same password that you enter for the "Incoming" (POP3) Mail Server in your e-mail software Account settings.
      See the List of Characters that are allowed in POP3 Passwords in the section "New e-Mail/POP3 Password" below, and the Password Inputs Note above.
    • New e-Mail/POP3 Password -- enter the new POP3 Password that you want to start using immediately here. You must also enter this same password for the "Incoming" (POP3) Mail Server in your e-mail software Account settings.
      Only the following ASCII (a.k.a. US-ASCII) Character Set characters are allowed in POP3 Passwords:
      In other words, blank passwords are not allowed; and, no spaces, control characters, or Extended ASCII characters are allowed. See also, the Password Inputs Note above, and the Confirm New Password topic below.
    • Confirm New Password -- reenter the new POP3 Password here to confirm that it is typed correctly. This step will help to prevent you from mistyping your new password, consequently locking yourself out of your own mailbox. See also, the Password Inputs Note above.
