I have no-ip.org which is similar to dyndns and employe reject_unknown_sender_domain and do not *seem* to have any problem with any mail. I look at the logs every morning and see nothing amiss. Neither works. :-/
Not "reject_non_fqdn_sender, nor "reject_unknown_sender_domain", nor /etc/postfix/access. The sender empty sender address, "<>" is not rejected :-(
Furthermore, reject_unknown_sender_domain rejects emails with false domain, true, except that then fetchmail simply doesn't flush them from the server, but leaves them there; with the result that they are tried on the next cycle, and I finally have to remove them manually.
The remedy is worse than the illness :-/
The difference being I an *only* talking about mail routed directly to my machine address, not that which is obtained from othe providers via fetchmail. I receive a *very* minimal percentage of spam on my machine that is actually addressed to my machine, wahoo. Most of the spam that I receive is obtained via fetchmail from arbornet, myrealbox, hotmail, fastmail and yahoo, and hotmail does a better job rejecting spam than yahoo. I get virtually no spam via swissinfo. *If* I had an alternate (backup) address for my own mx, I would dump *all* of the other providers, but except for my cable charges, I pay nothing for my email system. If I had to use tiscali as a provider, I believe that I would *only* use mail via another _free_ provider such as swissinfo, or somewhere I could get some a shell account and/or control provided for the mail system, ie: "reject_non_fqdh..." -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org HOG # US1244711 Photo Album: http://wahoo.no-ip.org/photos
