I think so. We're talking about the "from" box (blacksheep), right? I have this entry in my alias file on blacksheep and have run newaliases: root: drew@mykitchentable.net The attempt here is to redirect all mail to root (daily cron jobs) on the firewall (blacksheep) to my mail server (blacklamb) where I get the rest of my mail. It worked fine when I was building the firewall and only using one NIC (ed0 192.168.1.2). When I enabled the firewall as a gateway and put it between my ADSL modem/router (the ADSL box does NAT) to pass traffic between my private network (ed0) and the Internet (ed1 192.168.10.2) is when I started getting the connection refused messages. > check /usr/local/etc/postfix/main.cf and make sure you've set it up > properly. some things to look at: > > myhostname default > mydomain default > myorigin myorigin = $mydomain > mydestination mydestination = $myhostname, localhost.$mydomain, $mydomain > mynetworks mynetworks = 192.168.0.0/16, 127.0.0.0/8 > alias_database On the mail server (blacklamb), I have these two entries: root: my.logon drew: my.logon So mostly it is a default setup. This setup receives mail from everywhere except my firewall. And from your telnet suggestion above, apparently it even accepts "manual" mail from my firewall. Now I'm really stumped. > try setting "disable_dns_lookups = yes" to eliminate it being a dns > issue I added: disable_dns_lookups = yes and then issued postfix reload. Same problem. > personally I'd run postfix on both boxes. I may try it as a last resort. I just wanted to keep the firewall "standard" as it's not doing anything more than sending it's internal messages to root. Thanks for your help! I'd appreciate any other suggestions you may have.
