Hello HuskyBob,
I wrote the guide you are referring to.
When I wrote the guide, Nethserver couldn’t download email from a multidrop POP3 mailbox and route it to different users. Each POP3 connector must go to a specific user. I’ve had a look on the POP3 connector in the current Neth7 web console and it still routes POP3 accounts to specific users.
It still appears as though Neth7 does not support Multidrop POP3 for getting email from your ISP mail server.
The guide Howto setup a multidrop mail server V2 configures a separate linux server on your network to get the email from your ISP multidrop POP3 account and then route it to your NethServers email system. It’s a bit of a hack (needing two servers to run a basic email system) but it does work.
Regards
Bob
