The LDAP server is running on the same machine as Courier and I'm submitting the message via the sendmail interface on the server. So there are no firewalls (or other networking stuff) involved.I'm doing the testing like this: $ sendmail -f [EMAIL PROTECTED] [EMAIL PROTECTED] $ sendmail -f [EMAIL PROTECTED] [EMAIL PROTECTED] $ sendmail -f [EMAIL PROTECTED] [EMAIL PROTECTED] 450 Service temporarily unavailable. [EMAIL PROTECTED]: invalid address.
I'm wondering if the LDAP server forcibly closes idle connections. After the first authentication request, each process keeps the connection to the LDAP server open. The LDAP server may be closing the idle connection after some period of time, which results in an error when the same process eventually gets an authentication request.
Check the server's configuration for a similar setting, and adjust it.
