When I tried to get my modem/router to email its logs to a computer in my LAN, and went through similar problems. The router would try to use the DNS servers it knew about (the ones the ISP sets up through DHCP), and obviously they couldn't resolve my LAN addresses. But, I gather from your first message that your router is a computer, not a device, so your problem ought to be different. I think you want to check that each computer in the equation can resolve its own name, and the other computer's. Avoid using "localhost" as part of the mail addresses. On my LAN, I have a DNS server that all the computers use, and it has all the local machine names in its records. It solved a lot of name issues, and freed me from ever having to mess around with hosts files, again. The [bracketing] the IP address after the @ sign ought to work, to use an IP address without name lookups, but I don't know if everything does that trick. Where are you seeing the error messages? The SMTP server logs from where you're trying to send from, trying to receive at, or something else? Later on you mention a "user unknown" error. Are you accidentally trying to send mail out using your ISP's SMTP server? -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
