Batch File Contents


This is the content of the batch file:


NetMailBot.exe -receive -popheader 1 -popserver localhost -popuser -poppassword secret

  2. Open Notepad and edit the batch file "RetrieveHeader.bat". Change the values of the following parameters:


NOTE: The parameter -receive is required whenever using the POP3 parameters; this parameter puts NetMailBot into what might be called "POP3 mode" as opposed to "SMTP mode" which is for sending mails.

  2. An email message header from your POP3 mail server should be downloaded and saved to your hard drive with the filename "header[message number].txt" in a folder named "pop" under your System Temporary Directory.
