[Mailman-Users] bounces

[kalin m]

so if it's not 5xx it's not a bad email?  i see dsn=4.0.0. that's not 
enough?

i'm assuming it's retried by the mta. the settings in mailman clearly 
state that it should be discarded right away...


bounce settings:

bounce_score_threshold = 1.0
bounce_info_stale_after = 10
bounce_you_are_disabled_warnings = 0
bounce_you_are_disabled_warnings_interval = 0

not sure about the bounce_info_stale_after. the way i interpret this is 
that the bounce information will be kept for about 10 days in case the 
score rises. if i put this down to zero the score will start clean every 
day. is that correct? or is this the reason for the repeated log entries 
- lots of to=<vvv at zzzzzz.com> attempts...

here, from the maillog:
to=<vvv at zzzzzz.com>, delay=03:42:23, xdelay=00:00:00, mailer=esmtp, 
pri=785918, relay=zzzzzz.com., dsn=4.0.0, stat=Deferred: Name server: 
zzzzzz.com.: host
 name lookup failure

thanks...
