SMTP relaying/sending mail

[Robert Cates]

Hi,   I have a Debian Woody server running on a ADSL connection with (of course) dynamic IPs. I have the (default) Exim 3.35 MTA installed, and when I try to send mail to certain domains, it gets refused.  Some destinations are delivered, but most are not.   Is there a configuration change I need to make?  Do I HAVE to use a "Smarthost" from my ISP? Is there no getting around this problem?  Can't I use my Exim Server to send out mail even with dynamic IPs?   I've heard of a service (I believe in California) which is attempting to fight spamming by blacklisting IPs from known or suspected spammers, but this I believe is the wrong way to go about doing it.  I just want to run my own mail server.   All help will be greatly appreciated!   Thanks, Robert
