Have a quick question. I need to write a script that reads a list of data from a URL then writes that information to a file on our mail server. The reason I need this is to dynamically update our relay list so our internet customers can relay thru our mail server. This updates continually, and instead of changing our relay list when ever a customer complains of not being able to send mail I need a script that does it for me. Any ideas on how I should go about doing this? For example:

URL List contains:

10.10.10.0
4.0.0.0
4.0.1.0
4.0.2.0
and so on

I need everything in this URL list to be inserted into relay-domains dynamically.

Please help, I have a short deadline on this because the relay server we are currently using is being taken down.

Thanks in advance.

maybe you could use wget? If you need something more complexe you should look into something like Perl's WWW::Mechanize.

I think I may have it. What I have done is use wget to fetch the file from the URL. From there I cat the contents of local-relays (our internal network ip's) and the file I fetched from the url into relay-domains. Hopefully it will work as planned.
