Forum OpenACS Q&A: Re: unwanted spam from my server... help.

Posted by Deds Castillo on
rcpthosts contain the domains that you can send email to regardless of whether your box host that domain or not.  locals contain domains that are to be treated locally.  This means that on stock qmail, if you have a unix user "david" and your locals contain and, all emails addressed to and are to be treated as local and sent to the unix user "david"

I personally patch qmail with smtp-auth to take care of relaying.  relay-ctrl used to do the job but it allows relays via ip addresses...  this is bad news for NAT-based systems as one valid email user inside the network allows all others from that network to use your box as relay.
