I have a server that is running web and email services for some folks, One of the sties has their own exchange server, so I put this server's ip in the DNS as the MX record.
That was easy enough, now I notice though that when I use PHP to send mail from the web page to someone on this exchange server, or if someone using this server as an SMTP send mail to someone on the exchange server it doesn't get there. I'm using DBMail + postfix + mysql, and the transport table in Mysql has no entry for this domain, so dbmail should just ignore it and send it out to whichever host the MX says to, right? For some reason though, it's not getting through, and there's no entries for the mail send in the maillog file. Would I need to do something special to the dbmail configuration to allow for this or should it just work? I'm trying to get my hands on the exchange logs to see if that's rejecting it. -Micah
