Hello,
you was right, Sam. We are running courier restart every time we add a new "hosteddomain". I'm sorry I didn't realize before. What I had known is that "makehosteddomains requires a 'courier restart'. makeacceptmailfor doesn't." (you told the list on 2002-12-25), so everytime a new host is provisioned in our systems, our scripts run "makehosteddomains" and afterwards "courier restart". (This has to be this way, isn't it)
So this clarifies the "SHUTDOWN: Restarting..." messages. Thank you, Sam.
I am still worried about the "400 Service temporarily unavailable" errors, quite frequent. These errors appear from time to time, every 5-10 minutes. They are logged by courieresmtpd, both when receiving local mail and outgoing mail. This is why I think that the problem has to do with ldap aliasing. Yesterday we increased the number of courierldapaliasd process to 10 but the problem remains.
Which is the difference between 400 and 450 Service temp... errors? Both happen when contacting ldap, isn't it?
Maybe the OpenLDAP servers cannot manage all that connections?
We are balancing ldap requests to the 2 ldap servers via SSR routers. Maybe the SSRs are dropping some connections or requests?
Any idea, please?
(The current version is 0.39.3, quite old, so we've planned updating for the next week...)
Thanks for your help.

Well, you're running something. The specific message 'SHUTDOWN:
Restarting...' is logged only when something runs 'courier restart'.

Because you have a lot of messages left in the queue, so that there's a
scheduled delivery attempt every minute, or so.
