Notes

• Supports GIF, PNG and JPEG.

• Supports per user images (copies username.(gif|png|jpg) to portrait.(gif|png|jpg)!).

• Supports Outlook 2010 and 2016 (and probably 2019 and 365 as well)

• Plain text and HTML templates should be UTF-8 encoded!

• Settings for "-ini" are relative to the program's base directory.

• The field mapping is more flexible and no longer limited to the ones listed in the example configuration file, you can basically use any combination of placeholder and LDAP attribute.

• Features a new and more powerful template parser based on go's template package ("-newparser", fixed delimiter: "[[ ... ]]", have a look at the examples!).

• Relying on a GPO for setting the default signature on a company wide level should be preferred over the software's approach to manipulate the user's registry.
