SF checks if the host name of the sender resolves. It must resolve (or have an mail exchanger entry) because otherwise you cannot get bach delivery errors (bounces). Maybe your mailer sets the "From:" address correctly and fails to set the SMTP sender. What program do you use? If it send mail via sendmail, try to add the -f option to its command line: sendmail ... [EMAIL PROTECTED] ... Walter
