The easiest way to run it as a service is to use WinSW from https://github.com/kohsuke/winsw

Steps

1. Download WinSW binaries
2. Extract them to a new folder
3. Copy the IP mailer jar to this directory (like ip-mailer-1.0.0.jar)
4. Rename the winsw.exe to the name of our service (like ipmailer.exe)
5. Create the winSW XML configuration file (like ipmailer.xml)

<service>
  <id>ipmailer</id>
  <name>IP Mailer</name>
  <description>This service runs IP Mailer application</description>
  <executable>java</executable>
  <arguments>-Xrs -Xmx256m -jar "%BASE%\ip-mailer-1.0.0.jar" --ipmailer.serverHost=my-email-host ...</arguments>
  <logmode>rotate</logmode>
</service>

ipmailer.exe install
