I have a Mail --> PI --> R/3 scenario and I am configuring the Mail sender adapter for POP3. The issue is that the POP server is not configured to be accessed via a URL and hence the URL pop://hostname/ is causing the following error at runtime:
1. When I use pop://FQDN host name/
Error: exception caught during processing mail message; java.net.UnknownHostException
2. When I use pop://IP address of host:port/
Error: exception caught during processing mail message; java.lang.NullPointerException
I am able to ping the POP3 server from the PI server using both the FQDN and IP address.
Can someone please help.
