Configuration information can besaved in the registry.INSTALLATION:1) Copy the file "gwinsock.dll" to your "WINNTSYSTEM32" directory, or to any   other directory in your path. (Check if you already have it and only copy   the DLL if the date is more recent than the existing one)2) Copy the file "Getmail.exe" to your "WINNTSYSTEM32" directory, or to any   other directory in your path.3) Run "Getmail -install yourhost.site.blah.blah [email protected] yourpassword"   It's recommended to put a fake password in here, and then provide the password each   time you run Getmail, for obvious security reasons.   You can optionally specify some other parameters.  In order, then are "delete",   "Xtract", "Tries", "Port", and "Profile".  delete/xtract are either "-","Yes",   or "No".  Tries is a number, or "-" for the default of 1.  Specifying a "Profile"   will allow the settings to be saved with a different profile name.WHAT'S NEW IN THIS VERSIONversion 1.33    - Fixed inability to parse some mail messages properlyversion 1.32    - Added "-headersonly" option to download only headersversion 1.31    - Added "-domainstamp" option to attach sender's domain to each extracted fileversion 1.30    - Fixed extraction bug when an extraneous "Status" header appeared after Content- lines, but before message bodyversion 1.29   - Fixed minor bug with "-plain" extraction (occassional extra characters added to output)version 1.28   - Return code is now zero on successs, non-zero on error (used to be the number of     messages retrieved).version 1.27   - Unique filename generation changed to ensure that file extension does changeversion 1.26   - Added "-ti" timeout optionversion 1.25   - Getmail now generates non-conflicting attachment names for all extracted attachmentsversion 1.24   - Some attachments (from bulk mailers) were previously ignored.
