Re: ldap-mail-routing

[Matthew Schumacher <matt.s@aptalaska.net>]

Do you really want to do full-on ldap mail routing in sendmail?  Unless 
you have a couple of servers it's really not needed.  Sendmail will 
deliver mail to ldap users by default if nss_ldap has been setup to 
allow the system to resolve users against the directory.

I only have a single server so I just put in a ldap map in sendmail to 
resolve virtusertable against the directory therefore resolving every 
email address to a literal user.  In order to prevent sendmail from 
delivering mail to users that do not have a mail address explicitly 
defined in the directory, I had to write a rule that looks up every 
incoming email address and returns "unknown user" if the email address 
isn't found in the directory.

This caused my mail system to work exactly like post.office or netscape 
messaging where every email address is logically bound to a user or 
denied.  This also eliminates user conflicts.  As long as the username 
is unique and the email address is unique your good to go.

Hope that helps,
