do not resend Bounce?

First of all thank you so much for your open source OpenEMM, it is really such a powerful tool.

Just one question about resending boucing emails : is it possible to set up that I don't resend email that have bounced ? If I am correct, if there is a soft bounce, the email is resent several times and we hope that after a while it will succeed. Is it possible to say "I try to send the email, and if I receive the bounce information, I just put this adress on the bounce list but I don't resend it" ?

So if I have a 100.000 email list, I know that I will have 100.000 emails sent, and not 200.000 or 300.000 because of retry ?

Thank you very much in advance

Trying to send an email address that generated a soft bounce is standard practise of Sendmail which OpenEMM uses as MTA. For more info please see section 6.2 of the OpenEMM Install Guide.

Hello and thank you for your answer.

Do you think I can write

$sm -q1m -NNEVER -OQueueDirectory=$BASE/var/spool/QUEUE -OpidFile=$run/ -Otimeout.queuereturn=1m

to say that I want to retry only for one minute ? I guess that would mean that I don't resend :

1 / I send an email at 10:00
2 / I receive a soft bounce message at 10:05 for example
3 / 5min>1 min , so I don't resend ?

Do you think this parameter would be a good choice or is it a mistake from my part ?

Thank you in advance

I am thinking that if I am the only one asking this question, maybe I am wrong and resending bounce is not a problem ?

But I can't get why :)

Hi Laurent0106,

Although your question is somewhat older, other users may have a similar question.

Reducing the life-time of a mail in the queue to 1 minute is a problem for grey-listing processing.

Grey-listing means that a receiving mail-server tells your OpenEMM something like
"I don't know you and I don't want your mail. But I give you a chance to try again in 5 minutes"
OpenEMM will then resend the mail until it is accepted by the mail-server. Since the standard grey-listing time is 5 minutes (meaning your OpenEMM should try again in 5 minutes), setting the life-time to 1 minute prevents you from successfully proceeding grey-listings thus drastically diminishing your mailings success.

Hope this explains it well enough.

Best Regards

Our experience: For grey-listing you should not go below 15 minutes.

Hm, just checked the GUI and each change to forwarding bounce filters was written within a maximum of three minutes to file bav.conf. So, I wonder what went wrong with your installation. Did you use the frontend to create forwarding bounce filters?
