Assumpte: [exim] Why the temporary rejections?
Hi,

I am getting a few mails being 'temporarily rejected' but without
apparent reason. Is there any way I can find out why?

Reject log:

2004-08-29 04:46:47 H=dp.samba.org (lists.samba.org) [66.70.73.150]
F=<samba-bounces+ruth=ivimey.org@???> temporarily rejected
RCPT <ruth@???>

2004-09-02 14:16:23 H=wireless2.ivimey.org (Robinton) [192.168.0.9]
F=<Ruth.Ivimey-Cook@???> temporarily rejected RCPT
<hugh@???>


In the latter case this was a message sent from my domain (me) to an
address that is aliased to an external address. What makes it irritating
is that Outlook treats such rejections as permanent errors :-(


Extract from config follows (with comments and blank lines removed:

log_selector =  +retry_defer +skip_delivery +lost_incoming_connection
+smtp_syntax_error \
      +delay_delivery +size_reject +smtp_confirmation -smtp_connection
+connection_reject +delivery_size

callout_positive_expire = 4d
callout_domain_negative_expire = 8h
