Re: Mail server and address lookup by Sendmail using OpenLDAP.

[Kristina <kristina@fsas.fujitsu.co.jp>]

This is in reference to the original message I sent which is below.
I spent the whole day today trying to integrate mail500 into sendmail, which I
have finally managed to do...I hope it will run okay!

I still need some help on how to set up OBJECTCLASSES and attributes in LDAP
to use with mail500 and sendmail for my system which is described below.

Thanks in advance,
Kristina
