Thanks, smah. With my luck lately it's both. :>

Someone summed up my problem very nicely: if a message claims to be from a local address, but isn't being relayed from a machine on your network, the message should be rejected or discarded as a forgery. This is what I'd like to do.

Thanks for the response. I do use SMTP auth to prevent relaying, but that's not stopping local delivery from bogus local accounts. Here's what I'd really like to do: HELO spammer.com MAIL FROM:fakeaccount@mydomain.com *STOP* server sees this is a local domain and CHECKS if the user exists...

Okay, it's early, that topic made no sense. What I meant was: Stopping spam with forged headers to my domain

Spammers are smart. :/ I've implemented TMDA lately, and am giddy with the results so far...no spam has been getting through! However, I've noticed that the spammers have changed tactics now, and have received over 1000 spam emails that now are using my domain in the headers as the "From"...

This is true, however there has to be a way to identify which hostnames are *valid* versus *invalid* as far as mail delivery goes. Here's what I found.. I configured sendmail to relay mail for *individual hosts* only (thanks to Sendmail Cookbook, recipe 3.7). I did this by configuring the...

Hello all. I'd like to stop incomign email that contains a specific hostname, and I've not yet come across the way to do it in sendmail. For example, if my domain is xyz.com, I want to reject any mail that has a hostname in it: GOOD: postmaster@xyz.com BAD: someone@www.xyz.com...

I have been receiving a lot of spam mail directed to hosts in my domain (e.g. user@www.domain.com, gw.domain.com, host.domain.com, I.dont.want.mail.here.domain.com...). How do I stop this behaviour? The only allowable addressing I desire is user@domain.com, not any of it's hosts or subdomains...

Thanks for the input, CA. I couldn't think of anything else except that I was on a laptop which was logged into another server where I was tip'ping to this new one. I figured I'd pull all of that out of the equation and attached a Wyse directly to the new server. Of course it worked fine then...

Hey all. Could use some ideas here. I'm repurposing an old E250, starting with installing a fresh copy of OS 8. I've set auto-boot to false and have an OS 8 CD in the tray. When I try "boot cdrom - w" it hangs after the 'please wait' animation spins a few times: {0} ok boot cdrom - w Boot...

AHA! I think I found the solution... I'll post again after I try deploying it.

Thanks for the input, SQL. I believe KiscoKid also made that recommendation. However, I'm keen on making it work the same as my Netopia router had been doing, which was to allow me to use the external IP address successfully from inside. Seeing that the Netopia was able to do it, I can't see...

Hey SQL... Yes in both cases. DNS resolution is correct from inside, and no, I cannot connect from inside using the external IP address. However, pings to the external IP from inside do return okay. Traceroutes to the external IP of return 1 hop showing the internal interface as the only hop.

Thanks, sql. Yes, as mentioned, access from *outside* the LAN works fine to the external IP. It's trying to get to that IP address from *inside* the LAN that breaks.

Hey all. I'm still having some issues getting routing through PAT working the same as my old router. I have one external IP and am running 10-net internally. I have a local web server with URLs DNSed to the external IP. I'd like to be able to access them through their DNS names instead of the...
