[thelist] Basic sendmail question

[Brent Eades]

Hope this isn't too far off topic... anyway, I run a web server from 
home, using my DSL account to connect to the Internet.

Recently I had to build a new server after my old (ancient) one finally 
packed it in. I have everything working fine, except for one small 
detail: my CGI scripts that rely on sendmail have stopped sending mail. 
Or more to the point, my ISP has stopped accepting the mail. When I 
check /var/log/maillog after running one of these scripts, I see:

[snip] relay=to1.bellnexxia.net [snip] DSN: Service unavailable

... where 'to1.bellnexxia.net' is my ISP's SMTP server. (In other words, 
I need to use my ISP's SMTP server to relay the mail sent by the 
scripts.) If my hazy memory serves me, the 'Service unavailable' message 
means my ISP is refusing the mail.

I recall having to jump through some hoops to get sendmail working when 
I first set this stuff up years ago, but I forget the details. I have 
changed the SMART_HOST setting in my sendmail config to my ISP's SMTP 
server, and sendmail is successfully connecting. But I can't remember 
what else I have to configure to convince the server to accept the mail.

For reference, my ISP is sympatico.ca, and my Linux distro is Fedora 
Core 4. My web server connects to my ISP through a router. Any and all 
help much appreciated.
