Hello list, I have a problem with my spare mail-system. host -t mx mydomain shows: mydomain: MX 20 mx2.mydomain mydomain: MX 10 mail.mydomain So it looks like it should be and it works - when sending host cannot find my mail host it sends to mx2. Spare host however cannot send to mail host and it does not wait til the mail host is reachable. Instead it logs DNS problem and sends email back to sender. How to tell spare host to queue such emails and resend them when primary host is on the line ? PS. the spare mail-system is running sendmail, if it has any meaning. -- Regards, Marek L.
