Not being a programmer at all I thought I'd put this out there;
Has anyone thought of making a 'whois' zimlet?
Hover over an IP address (like in e-mail headers which I do regularly) and get a little pop-up with the whois results...
Be a cool little tool, don't know how popular though :)
I was just thinking about this idea as well, Maybe have a zimlet that can do whois lookups on IP addresses in the mail header, domain names, but also IP/domains in the body of the email,
A hosting company could use this as they would then not have to do a whois lookup in console or on the web but just on zimbra itself,
