NB I am replying to Scot's mail but this is actually addressed to everybody who was patient enough to reply to my fuzzy headed muddling. I was indeed sending mail directly to the RedHat servers. I had missed this simple explanation of the problem for about 3 months now, the information in the mail headers simply did not register. Also I still do not understand exactly what was wrong with my postfix setup. I did have quite a complicated setup with a recipient_canonical and transport tables (because I used aliases for my home network). But I don't understand why the transport table would lead to bypassing my ISPs smtp server. Anyway I have drastically simplified things and now use only a sender_canonical table. This email should now be relayed throught my ISPs smtp server and my troubles (except maybe for occasional greylisting, which I shouldn't notice now I expect) should be over. Everybody thanks again Alexander
