Thanks Ray, but I actually did those searches before i posted, but I didn't think the answers looked like solutions.
§1 Anyway, I did the command
/etc/startmail
and it turned back nothing (I'm unsure if that's good or bad).
§2 I looked over my fetchmail (contrib) account settings.
§3 I did the command
/sbin/e-smith/config show fetchmail
and it turned back
fetchmail=service
FreqOffice=every15min
FreqOutside=every15min
FreqWeekend=every15min
Method=standard
SecondaryMailAccount=popaccount
SecondaryMailPassword=poppassword
SecondaryMailServer=mail.myisp.xxx
status=disabled
Note that status=disabled even though Fetchmail are enabled in server-manager (and I did a disable+enable, and then checked again with same result).
But then I realized that this is maybe only the config, not the current status?
§4 Trying Windows solution 1: Reboot.
Lets wait and see if any of these actions helped....

-No, another #***-mail was sent an hour later.
I'm all out, ideas anyone please?
