Hello Benoit, > Have other seen this behaviour of exchange servers
Yes. One of our MX servers somehow managed to loose the connection to the ldap server (didn't dare to re-establish it) and only returned (valid) tempfail messages. Sending mails from Exchange (internal messaging system) to this MX server produced the same strage error messages. Using snoop i could verify that the MX server did NEVER send a 550 error to the exchange server. > and know how to prevent it? No idea. > The strage thing is this only seams happens occasionaly. In my case it happened always. Regards, Adrian _______________________________________________ swinog mailing list [EMAIL PROTECTED] http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
