Hi

I have the following router in the config file.

special:
driver = manualroute
transport = remote_smtp
route_list = optimalprofit.com nt-opro-h0.gdmckee.home

It works fine. All mail to *@optimalprofit.com goes to the mail server on nt-opro-h0. The problems occur when the mailserver on nt-opro-h0 is down. Exim sends all the mail to smtp.blueyonder.co.uk instead and then it seems to get lost and I never get the mail. I guess it is picking up the blueyonder bit from the following rule in the transport section of the config file.

remote_smtp:
driver = smtp
fallback_hosts = smtp.blueyonder.co.uk

It there a way that I can get exim to store the mail for optimalprofit.com and deliver it when the sever comes back up?

Thanks in advance

Gordon
