Thanks for replying. Ok no problem with this explanation, i'll try this smtp_mx_session_limit parameter. Howerver, and it has still happened few minutes ago, does it prevent Postfix to "vomit" all deferred mails and make the IP blocke again ?
You say that slow donw apply wherever mails come from, ok. But the exact behaviour i can watch is : - when deferred queue is empty, with mails arriving from classic incoming queue, sending is "delayed" - when deferred queue has mails (even not many), Postfix requeue it, and IP is BL few minutes later It is possible that something is not tuned in our config, but what ?
