If LDAP is used for address lookup and if the LDAP lookup fails due to
either network or server errors then the mail messages will be queued
including those messages addressed to root. This is not acceptable as
mail messsages addresssed to root need to be delivered immediately as
they could be messages about system panics.
A work-around solution to this problem will be to comment out the "CL"
class macro in the sendmail.cf file as follows:
CL root
By using the above directive only mail messages that are queued up for
user "root" will be delivered when there is an LDAP look-up failure.
However, if you wish that mail messages addressed to some of the other
local users on the server be deliverd too, you can do so by using the "CL"
macro. For example:
