Hi,

I'm having the same problem that's described here but isn't pratical to change my mail aliases file.
I was wondering if setting minimum_bouncing_count <http://www.sympa.org/wiki/manual/conf-parameters/part3#minimum_bouncing_count> to 1 and minimum_bouncing_period <http://www.sympa.org/wiki/manual/conf-parameters/part3#minimum_bouncing_period> to 1, and setting Bouncers level 1 rate to 1 could it be possible to know in 24h who didn't received some of the message posted. On the other lists that I don't want to know in 24h if someone received some message I maintain Bouncers level 1 rate on 45. Could this work?

Best regards,
Luís Sousa

Hi Brian,

Brian Riffle a écrit :
In the list config, under management of Bouncers, there is a default threshold of 45 points. We have a list that has sent out 3 emails, all 3 bounced to the same user, but they show "0" points. How is this calculated?
The algorithm used the compute the score is explained in the documentation : http://www.sympa.org/wiki/manual/bounces#bounce_management

The score evaluation main parameters are:

*
|Bounces count|: the number of bouncing messages received by
Sympa for the user.
*
|Type rate|: bounces are classified depending on the type of
errors generated on the user side. If the error type is
|mailbox is full| (i.e. a temporary 4.2.2 error type), the
type rate will be 0.5, whereas permanent errors (5.x.x) have
a type rate equal to 1.
*
|Regularity rate|: this rate tells whether bounces were
received regularly, compared to list traffic. The list
traffic is deduced from the |msg_count| file data.

The score formula is:

Score = bounce_count * type_rate * regularity_rate

To avoid making decisions (i.e. defining a score) without enough
relevant data, the score is not evaluated if:

*
The number of received bounces is lower than
|minimum_bouncing_count| (see minimum_bouncing_count

<http://www.sympa.org/wiki/manual/conf-parameters/part3#minimum_bouncing_count>).
*
The bouncing period is shorter than
|minimum_bouncing_period| (see minimum_bouncing_period

<http://www.sympa.org/wiki/manual/conf-parameters/part3#minimum_bouncing_period>).

You may have a bounce score of 0 if the user started bouncing recently or if he did generate a low amount of non delivery reports.
I know this score of 0 is confusing ; we'll try to make this information more straightforward in future relesases of Sympa.
Also, is there a way I'm not seeing to send the owner an email on every bounce? We want our instructors to notify the students in class to update their email address. We have found that some large ISP's will start marking all emails from our domain as spam if we attempt to deliver to too many invalid emails on their system.
You can get this behavior if you disable the automatic handling of bounces by Sympa. All you have to do is change the <list>-owner mail alias as follows :

mylist-owner: address@concealed, address@concealed
