Here's my situation:

I have a network at home that uses a slackware server as the router. Therefore when I connect to another computer on the internet it shows up as connecting FROM my servers IP. (lets use 111.111.111.111 as my home server for now)

At work I have the same exact kind of network setup with a slackware server as the router as well. (lets call my works server 222.222.222.222) I use my home server for webhosting and have my work server setup to redirect there. (Due to lack of space)

This works perfectly, but now I am trying to setup my works server to be my outgoing mail server for all my computers on my HOME network. As of right now, all the computers behind the server at WORK use the server as the outgoing mail server and it works perfectly. I accomplished this by putting in my local IPs in the relay-domains file. (192.168.1)

I then added the ip address range from my home server (111.111.111) to relay-domains. However, when I try to send an email from home, the work server gives me a relaying denied error. I tried to be more specific. I put 111.111.111.111 into the relay-domains file (on my work server). Still gives me the same error.

How come my work server redirects emails from all the computers internally on my works network, but denies all emails coming from my HOME network? I have the IP address entered correctly in relay-domains


Any help would be greatly appreciated! Thanks in advance.

have you looked at domain routing?
mailertable

Are you sure you don't have those relay entries in /etc/mail/access? Thats where I would put them.

BTW: When you add entries to the relay-domains file, sendmail would need to be bounced. When you add entries to the access file, sendmail does NOT need to be bounced, just rebuild the access database.

I am using an older version of sendmail that did not already have /etc/mail/relay-domains or /etc/mail/access. I had to create both files myself. I first created /etc/mail/access and it did nothing. (probably because I did not rebuild the database, since there was no database there in the first place) I then created relay-domains and deleted access. This worked perfectly for my local network, but not external.

After some tweaking and rebooting of my works server, I finally was able to get my home computers to use it as an outgoing mail server. (I think) I have not fully tested it yet. Apparently it only works if you put the EXACT IP address in. Not just a partial IP for the external network.

Lastly, my mailertable file has nothing configurable in it. Here's what that looks like, let me know if you see something configurable:::
