Hi I have a problem with one e-mail hosting and I need to slowly him example: That's hosting send to my users e-mail (normal e-mail, not spam, sometimes mailing) but sometimes user not exists (because user was deleted) or user have quota - my server (Mailer-daemon) sends returns - and external hosting limit incomming e-mail per IP
I can limit the number of e-mails sent to them with: onet_destination_concurrency_limit = 10 onet_destination_rate_delay = 1s I thinking about limit incomming e-mail from thats domain or ip - and if the limit is exceeded, they will get 4xx information about exceeding the limit --
