Dear All, Yesterday i noticed that one of our smarthosts wasn't delivering mail anymore. Soon saw that both Domain Controllers that are being used for ldap lookups where down. Changed the ldap lookups to new domain controllers, immediatly afterwords the postmaster mailbox started to fill with these errors.
Transcript of session follows. Out: 220 server ESMTP Postfix In: HELO host Out: 250 server In: Mail from:<em...@address> Out: 250 2.1.0 Ok In: RCPT to:<em...@address> Out: 451 4.3.0 <em...@address>: Temporary lookup failure In: QUIT Out: 221 2.0.0 Bye Now i know that this is because we have "notify_classes = resource, software" enabled in main.cf Is there a way to limit the amount of warning mails that are sent? At the time we noticed the problem (US turned off their DC's while it was night in Holland) we received 350.000 warning mails in the postmaster box. I ended up in deleting and recreating the Postmaster box....
