Why is cron generated mail for root being relayed to my providers smtp server when using postfix? (At least after configuring postfix's main.cf to account for myhostname, mydomain, myorigin and masquerade_domains and using mailadress rewriting via sender_canonical_maps) If I remember correctly this did not happen with the default sendmail setup. Was internally generated mail for root even being delivered by sendmail/postfix/exim in previous redhats before RH9? Alexander
