[Mimedefang] Validating Exchange addresses

[Dan Tulovsky]

But the "mail" attribute contains only the primary mail address of the
user, not any of the aliases.  You need to get the proxyAddresses
attribute, filter out only the ones that start with "smtp:" and check
against all of them.

Unless, of course, your users all have just one valid email address,
then the "mail" attribute is just fine.

Be nice to your LDAP server and only request the mail attribute.  Your
ldapsearch command would then look like:

ldapsearch -h $server -x -P2 -s sub "objectclass=*" mail

Be nice to your LDAP server and only request the mail attribute.  Your
ldapsearch command would then look like:

ldapsearch -h $server -x -P2 -s sub "objectclass=*" mail

If you stick a '-LLL' in the ldapsearch command line, then you'll have
even less work for awk to do, as the output will look something like
this:

dn: blahblahblah
mail: foo at example.org

dn: blublublub
mail: bar at example.org

...

A quick browse through the man page doesn't show me a way of removing
the DN lines from the output, though, so I think you'll still neet that
awk statement.
