So far, I have yet to figure out a way to implement this kind of feature on
|
|
Linux workstations. The internal address scheme could probably be handled
|
|
using Netscape as a mail client and an LDAP server, but I don't know how
|
|
we would handle the external address book.

The functionality you refer to is of course implemented on mail servers,
|
|
not upon the workstations (client PCs). For example the SMTP server program
|
|
Sendmail, has "aliases" which provides the functionality you seek. See the
|
|
on-line manual entry: "man 5 aliases".

I used LDAP both at home at at my office to create a shared address book. I update the address book using a browser and the "ldap-abook" package. Ldap-abook is a perl CGI script and module that make it easy to update an LDAP address book.

I use <A HREF="http://www.redhat.com/">Red Hat</A> Linux 6.2, which comes with OpenLDAP almost ready to run.

The hardest part was exporting the data from whatever format it was in to an LDIF file for import by the LDAP server. After that, I customized the CGI script that came with ldap-abook to improve the appearance of it's HTML output. It works just fine.

I don't think I'd want to maintain a 300 entry "Aliases" database (And

that's just my personall address book!),...

........ nor does this provide the address
|
|
look-up capabilities that Outlook and Exchange do together. I can even use
|
|
my Address Book from the Exchange Server to insert addresses in postal
|
|
letters in Word, but what I'm really after is the ability that Outlook and
|
|
Lotus Notes have to automatically look up (and optionally complete) names
|
|
and/or addresses during message composition (or immediately on send, keeping
|
|
the message open in then event of a lookup failure).

It seems I misunderstood what you are trying to do. You are looking for
|
|
something which is tightly integrated with MS applications. Indeed, sendmail
|
|
e-mail aliases won't help you there.

Anthony Greene has suggested ways to connect Outlook and Netscape/Linux
|
|
clients to an LDAP database as a partial solution. I'll have to look more
|
|
carefully at how such an interface manages addresses (things such as adding
|
|
and updating), but Anthony's pointers may supply at least part of the
|
|
solution.
