So, I presume that they have been changed from a config file at some point, though which one I don't know. The question now is how do I set them back to postfix? Is it done from a config file, or by deleting the link and making a new one? If this is so, I presume that all the mta-related links will need changing? Sorry if this seems so very newbie, but after four years with a distro that does things very differently I do have a lot to learn. Anne
