I want drop one my domain name (I can't use one my old domain name). I want make some temporary change in my configuration. If qmail receive (via SMTP) mail with address having this old domain name send automaticly to sender mail-info (eg. You use old name of our domain (xxxx), Your mail was delivered correctly, but next time send mail using domain YYYY). But I want delivery all mail to user. I can't add to all aliasses .qmail-* some line (commands). I want make some preprocessing every mail (send or not bounce) and next make standard delivery. Robert Skup [EMAIL PROTECTED] PS. Maybe temporary changing qmail-smptd (add some linie) is not stiupid ?
