Dear all, First thx for your help, I implemented a slow mail queue to yahoo in my Postfix 2.5.5 installation. I encountered this issue, some emails to yahoo queued up (just 10 message) at active queue without delivery attempt for 1280. I don't sure why cause it. So I try to manually delivery one to yahoo by myself, and this one delivery immediately and then trigger the else with 1280+ queue time in active queue to be deliverred at the slow mail queue.
Before this server goes live, I tried with 1750 messages at a time to yahoo and all delivered withtout this issue for a period of 2 days. This one, the client delivered by 2 batches, 10 for each, the first batch was delivered, but after 2 minutes the second batch started but queued at active queue without delivery attempt. Please refer to the following log message. (I have NOD32 content filter installed.)
