I messed up with DMA mail agent as automatically installed SSMTP as I have done for each server rebuild and did not trust the SSMTP delete to reset the everything its installation would have changed, so re-installed the base OS again from scratch.
At least using Packages now (also weaning myself of using ports as not using cutting edge versions or complex needs) its very quick to rebuild and once I have SUDO and WEBMIN installed its nice and easy to quickly build.
Samba was a bit of a pain as FreeBSD is lagging so far behind the main branches supported by Samba so even the latest version (4.20) is out of support. Anyway.. its installed and works so that will have to do.
