This is on my home server, which has a mailserver to forward status reports (run by fcron) from itself and my desktop boxes to me. All other incoming mail is via fetchmail. My outgoing mail has been going via my ISP's mailserver for some years, ever since lists started to decide they didn't want to talk to a random broadband home user's mailserver.
In the end, I just copied the rules and key from the host. It's now booted and running - I'd not realised how much of my server-only build needs to change, mostly related to the bootscript changes since 6.8. Getting there, managed to get some updated rules. Meanwhile, it looks as if sa 3.4.0 is about to be released - I hope to rebuild my server if we have a BLFS package freeze for 7.2, so I'll give it a try then. Perhaps in a month's time I'll have forgotten some of the aggravation involved in getting the rulesets ;) ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-chat FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
