For several reasons, it seems like a good idea to build my own email server now. I've put it off for long enough, but I suspect that as my online life gets more complicated it's something that I'll find increasingly useful.
So I put a new Fedora box together tonight and started up sendmail. Problem - I can connect to 127.0.0.1, but not from any remote host. It's not the firewall (I keep having to re-learn iptables on a weekly basis), the port is open, but nothing responds.
Eventually, I read the instructions - is it a deliberate 'gotcha' to restrict the server from responding to anything other than localhost in the default configuration? A one-line fix to sendmail.mc, recompile and it's working. Approx 3 days quicker than qmail.
