and send message :
Here's a typical log sequence for a message sent to a remote system from the local system:
1 @4000000038c3eeb027f41c7c new msg 93869
2 @4000000038c3eeb027f6b0a4 info msg 93869: bytes 2343 from
3 @4000000038c3eeb02877ee94 starting delivery 2392: msg 93869 to remote email@example.com
4 @4000000038c3eeb0287b55ac status: local 0/10 remote 1/20
5 @4000000038c3eeb104a13804 delivery 2392: success: 18.104.22.168_accepted_message.
6 @4000000038c3eeb104a4492c status: local 0/10 remote 0/20
7 @4000000038c3eeb104a6ecf4 end msg 93869
Line 1 indicates that qmail has received a new message, and its queue ID is 93869. The queue ID is the i-node number of the /var/qmail/queue/mess/NN/ file--the queue file that contains the message. The queue ID is guaranteed to be unique as long as the message remains in the queue.
Line 2 says that the message is from firstname.lastname@example.org and is 2343 bytes.
Line 3 says qmail-remote is starting to deliver the message to email@example.com, and it's assigning the ID 2392 to the delivery.
Line 4 says 0 local deliveries and 1 remote delivery are pending.
Line 5 says delivery 2392 is complete and successful, and it returns the remote server's response, which often contains information the remote mail administrator would find helpful in tracking a delivery. In this case, the "CAA01516" is the remote system's delivery ID.
Line 6 says 0 local deliveries and 0 remote deliveries are pending, i.e., the delivery is complete.
Line 7 says that the message has been delivered completely and removed from the queue. At this point, the queue ID, 93869, is reusable for another delivery.
