My setup is using the defaults, but the connection is so flaky that even pings don't return consistently. My current setup no longer delivers mail, but I get lots of timeout errors, and it looks like most messages end up in the defer queue. Any ideas? This is a highly political situation and the people responsible for fixing the problem will not work with me, yet I am responsible for the proper functioning of this email system. Anything that even has a slight chance of working will be greatly appreciated. To give a better picture of the setup, I have a professional-grade multifunction device that scans, faxes, prints, copies, etc.. It has a fixed IP on the LAN. Its scans go out to the postfix server, which is connected to a Cisco switch, Netgear firewall, and Cisco router/CSU/DSU. I have authentication turned on and it only accepts mail from the multifunction device. It's not a high-traffic system- it just occasionally has to send a few scans over email. I have administrative access to the whole network, except the router/CSU/DSU (but any changes can be requested if needed). Any advice that can mitigate the poor line quality is appreciated.
If the network is that bad, and the people in charge of it don't consider it to be a problem worth fixing, get a dialup account somewhere and use good, old fashioned PPP. That assumes you can get a "good" dialup line, obviously. When your justification is that it would provide a more reliable Internet connection than your LAN, perhaps it would have the side effect of getting your network fixed.
