It's specifically this reason that the filters I wrote here (front-ends to sendmail, sorry, not sendmail.cf rules) specically permit mail to postmaster, even when normally mail would be refused otherwise. Error messages also refer to sendmail "postmaster" email. I would *think* that sendmail rules could also be written to permit mail for postmaster for domain level MAIL FROM:/RCPT TO: blocks, but I'm not a sendmail wizard. -- Jason Fesler jfesler@calweb.com 'whois jf319' | When the chips are down Admin, CalWeb Internet Services www.calweb.com | The buffalo's empty Junk email returned in bulk; 1 cc to your postmaster | Junk mail probs? http://www.gigo.com/junkmail.htm | :-)
