    3. OpenLink Mail Drop program
  2. The working schema is:

    Internet->SMTP Server(*>Mail Drop App (via odbc)->Virtuoso DB message

  3. You need to configure a SMTP server to receive messages for your domain name and execute mail_drop application for every incoming mail message to this domain. For reference see the steps below.

For Windows installation

  2. The files maildrop.dll and virt_mail.exe you can found in your Virtuoso installation folder.
  3. Place the files from above in the Virtuoso Server folder and execute:

    register.bat /register

  4. As result will be registered a rule in your MS SMTP server which means:

    "If incoming message is for domain, then execute virt_mail.exe"

  5. Configure the SMTP server so to add as alias or as default domain name. This can be done via Internet Information Services Administration:

    Start->Settings->Control Panel->Administrative Tools->Internet Information Services.

Step 4: Configuring WebMail application
  1. Go to http://[host]:[port]/ods
  2. Login as dav user (default password is dav)
  3. Go to Site Settings->Server Settings and configure domain names list with available domain for user registrations.
  4. Check if in the list "Existing Hosted Mail Domains" there is your domain, for ex. If not, add it.
  5. Logout as user dav.

Step 5: WebMail UI

  1. Go to http://[host]:[port]/ods and register a new user.
  2. Go to WebMail and create new instance. In the create instance page you need to provide domain from the list of available domains for your email address.
