server name is: rabbit.domain.com
my email address is: [EMAIL PROTECTED]
I have an ldap entry for the user john.smith, and a cyrus mailbox for the user john.smith.
If I set up ldap w/ a mailHost of rabbit.domain.com and a mailLocalAddress or mailRoutingAddress of [EMAIL PROTECTED], won't it just loop? How can I configure sendmail to deliver to my cyrus box on the same system. Am I missing an ldap attribute?
Thanks. AJ

The way you have it setup now Sendmail accepts all mail before trying to deliver it via cyrus (just like most secondary and some primary mx servers do). So if I send 1000 emails to non existant users your sendmail will accept them all (regardless of weather they exist or not) before trying to deliver them to cyrus. Because I'm a spammer I've used fake return addresses so you now have 1000 bounces sitting in your mail queue (which Sendmail keeps trying to resend every hour)until they expire putting a strain on your resources.
Every time I have setup LDAP routing for a domain (primarily on the mx servers but also on the cyrus system) it has resulted in a 80% to 90% reduction in mail traffic and server load.

Thanks. I have reviewed the sendmail page numerous times, but my question is what is the difference between the way I have things set up now, i.e just using cyrus as a local mailer, as opposed to ldap_routing. I am not sure why one would go one way or the other, just trying to clarify.
Thanks. AJ

My setup is cyrus, sendmail and openldap for all users data. The way I have things set up now is sendmail use cyrus local mailer, and is not compile w/ LDAP support, so if a mailbox does not exist in cyrus, it gets bounced. Sendmail does not do user/mailbox lookups via LDAP. This seems to work ok, but on the net I have been reading most people set up sendmail to look at ldap for users, rather than cyrus. Can some people share their setups on how they implement these three together?
