I encountered this a few times. Whatever I've put in server manager, the info wasn't saved. I played around with /etc/fetchmail and /etc/startmail.
take a look at /home/e-smith/configuration and search for the line fetchmail. There should ne an entry to your ISP or the default. Change this to the correct value and save. Doa console-save after that. (/sbin/e-smith/signal-event console-save)
