Hi OK I've read with interest some of your replies. It would seem that what I have actually been doing is rejecting any emails sent to me whereby the user is not registered on my server.
It would seem that the option in my server manager panel that handles postfix and that I thought was bouncing them back was not! It is actually sending a reject code 554 when the user is not recognised to the originating server. I did not realise it did this and only found out by asking on the user forum for my server's version of Linux. I was only coherently able to do this because of the helpful comments I gleamed from this list! Just goes to show my server has been very well set up, with fools like me in mind, so we don't make monumental admin screw ups! I am sorry about my loose terminology which I think may have been the cause of all this. However in my defence it did spawn a useful dialogue. Basically my home network (for those interested) consists of - 1 x Linux server 2 x Mandrake 10.1 Official workstations (for me and the wife to do most of our computing - these are the only machines that have been set up to get e-mail) 1 x Winblows box (I use some complicated mapping software that won't run under wine, and also a Internet database of Rights of Way that I use is only compatible with IE. For some reason the scripts just won't work properly in Mozilla and there are too few Linux people using it to justify the creators spending the time to fix it. Not ideal but I can cope with it as I have to have the machine for the mapping software anyway) I use three accounts for email. Two of them are used for lists and public forums and are pop accounts. One does all the computer related stuff and the other handles all the other misc interests I have :-). The last one is my own private addy that is on my server and that I am careful who I tell about! My server does receive mail direct. I have to use my ISP for SMTP to send mail from this particular address, or as I found out it in another of my learning curves, it ends up getting reported as spam! I have ClamAV installed on the server and I also have Spam Assassin but I think I need to do some research as I don't think I am using it to its full potential. Anyway it seems to have done the trick as the problem seems to have resolved itself.
