Hello. I am a newbie using OpenBSD 3.6 on a Mac G4. We are using this system as a DNS server, syslog and sendmail server for a small network of about 20 windows computers. We want this system to allow external requests for local services 1-SMTP 2-SYSLOG like sending and receiving email, receive system logs from Cisco equipment. Email is working only from the local server to local users. I can telnet to a external Exchange server and send emails with no problems but that's it. Sendmail can not deliver email by itself to the outside world.

Here is the output of the netstat -a following by mail -v and a maillog at the end. I have been researching this problem in many websites, books and articles and so far nothing. Any help will be appreciated.

Are you talking about the BSD beneath Mac OS X? Or have you scrapped Mac OS and installed pure OpenBSD?

If Mac OS X, then it has a built in firewall that is closed off by default. You have to specifically open it up from the sharing control panel, and you may have to create new entries for what you are doing.

Is a pure OpenBSD box.

I'm getting this error message also: "could not listen on UDP socket: address is in use." Please I need help.
