Good morning community:
We are having a very annoying issue with a qmail-ldap 1.03 implementation with approx 30k mailboxes. Suddenly, the users begin to receive an error like "451 mail server temporarily rejected message" when they try to send from webmail or desktop mail client. The qmail-smtpd sockets remain open, and the only workaround is to restart the service. We haven´t found evidence of spam attack, but the issue is occurring now every day.
We really appreciate your help, because is hitting our production system.
Thanks
David Espejo
