Hi Gavin,
I am also a relative noobie, and I tried to get this rpm to work without success, where did you get the rpm? I downloaded it from the e-smith.org/contribs site.
I am using a cable modem to connect to the internet, what are you using? I received an email from Stephen Noble telling me that this version didn't work with cable modems. So I installed Vincent Filalis multipop rpm on my test server, this worked OK but I never got it to sort out the email that was sent to a catch all pop3.
I have purchased the latest version from dungog.net and I still couldn't get it working, so I have emailed Stephen and I got a prompt reply with some settings, I will try these and see. If you're using a dial up modem then the version you have should work, I think. Any how the account in red is the first one that is setup in the email retreival panel in server-manager, if you set up one of your wildcard accounts here it will get checked, downloaded and distributed to the users by sme (this works great, but for only one pop3 account). On the dungog.net option "multiple pop3's" there is a link that says "Click here" to add a pop account for mail collection. You just fill in the server, user etc and if you want the email to go to a dedicated user put that in here also, if you leave a * in the deliver to box it should sort out the mail as the default one does. Stephen told me to check the status box. I haven't tried this yet and I will try to get round to it tonight and I will post the results here. There is some info on the dungog.net web site.
Hope this helps,
Del
