I thought I would resend this as it may be old and nobody looking at it, if not and I am just being ignored then my aplogies :-)
My scenario is as follows: I have an SMTP server setup to relay all mail to a server on the internet that does virus and SPAM scanning as well as adding the relevant disclaimers to emails. I have certain emails that cannot be altered by disclaimers as they have to be a in a particular format and the disclaimer server adds the standard disclaimer to all mails. Now these mails are being sent from particular addresses to many diferent recipients and these are the emails that I need to have sent directly out and not relayed via the other server. I know the format for the sender_dependent_relayhost_maps files is as follows: [EMAIL PROTECTED] server.somedomain.com How do I setup my sender_dependent_relayhost_maps file that will take all mail from the address [EMAIL PROTECTED] and then take the domain of the recipient address, do a lookup for the MX record and then send it directly to that domain's MX. For the next address it would do the same process and check the MX and send to the destination address MX record. Is there a way that you can tell it to send to SMTP as you can in the /etc/postfix/transport file such as "[EMAIL PROTECTED] smtp: " ?? Many Thanks in advance Wadeegh
