Uwe> This has been done, for the information of the people on this list. So here is the public follow-up: we were able to identify how Uwe should modify his sendmail configuration to fix the problem, but not the specific underlying problem that caused it. The default sendmail.mc for Solaris is: VERSIONID(`@(#)sendmail.mc 1.11 (Sun) 06/21/04') OSTYPE(`solaris8')dnl DOMAIN(`solaris-generic')dnl define(`confFALLBACK_SMARTHOST', `mailhost$?m.$m$.')dnl MAILER(`local')dnl MAILER(`smtp')dnl LOCAL_NET_CONFIG R$* < @ $* .$m. > $* $#esmtp $@ $2.$m $: $1 < @ $2.$m. > $3 By deleting the confFALLBACK_SMARTHOST line and regenerating his sendmail.cf, the problem went away. I suspect something subtle in his DNS configuration, but could never track down exactly what it was. Something resulted in the DSNs (no, that's not a typo: Delivery Status Notifications) changing from a 4.y.z (temporary) to a 5.y.z (permanent) error, thus leading to the bouncing instead of queuing that Uwe reported. Given that we found a working configuration, I am suspending my investigation into this issue, though I may resume it if at some point further data sheds enough light to allow me to proceed. Meanwhile, I wanted to let everyone know that Uwe was not hallucinating :-) as sendmail really was behaving as he observed. -- John http://blogs.sun.com/jbeck _______________________________________________ sysadmin-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
