Re: make mlmmj silent about delivery problems

thanks for the response, it seems like I am quite slow to.

the problem is, I don't really know much about mailserver and
configuration.

I have looked in /etc/postfix/main.cf

and I guess that these values are interesting, perhaps some of you can
recomends some better values.

bounce_queue_lifetime = 2d
minimal_backoff_time = 1800s

would it be better to increase this minimal backoff_time to.. say 1hour,
and maximum to 4 hours?

also, transport_retry_time is not specified, I am running postfix
version 2.5.5 so this seems like it will be 60s

there are no /etc/postfix/bounce.cf, I am not sure if this is important.

Furthermore, this doesn't happen for a lot of customers, we have arround
10k subscribers for a (almost) daily mail. We do get few complaints
about this (1 every 1 or 2 week) the last one complaining actually
contacted the police :(... now unsubscribed.

help needed: mails are not sent from remote clients

Hi there,

 

I can't get the mailing list up and running.

Let me describe the situation.

 

Sending a mail to the mailing list on the local machine itself is successful. That is what maillog says:

If I send a mail from a different host to the mailing list it is not forwarded to the recipient, although it gets stored in the archive directory. That again is what maillog says:

This seems to indicate the message was indeed delivered successfully
(accepted by the remote server). Maybe it has been classified as spam or
junk or something by the recipient server, after accepting it, or by a
mail client?

Re: make mlmmj silent about delivery problems

Hmmm. Seems OK to me. If you haven't messed with it, it is probably OK.

So maybe something specific about those addresses is causing problems.

Maybe look in the bounce subdirectory of your listdir. If probes are being sent 
there should be a 'last bounce message received' stored in there, I think, for the 
relevant addresses. That might shed some light on what's happening.

Ben.
