Wow, it's been a long while since I've heard of Siebel. Its a CRM application if I recall correctly, and it holds everything inside SQL tables, so in theory at least, it's completely possible to have a good level of intergration between Zimbra and Siebel, it all depends on what you want.
If you have a customer account code that can be recognised by a regex, then you could have a zimlet that would show customer details like address and support status, when hovering over such a code in an email. For example.
There is some good documentation for writing such things, and examining how existing code works is helpful too. Have a go and ask a specific question when you get stuck. |
