Hi, now my problem is solved but I have understood properly which was the solution for my problem ! I have modified the values in this mode:
$max_servers = 15 and smtp-amavis unix - - n - 10 smtp ..then I have increased memory available for mail server to 4 GB and then I have rebooted machine (also I have rebooted esx host), now the queue is empty and I have these resources available: [r...@mail ~]# free total used free shared buffers cached Mem: 3894828 3449876 444952 0 154920 2385728 -/+ buffers/cache: 909228 2985600 Swap: 2104472 68 2104404 I must add that I use Maia-1.0.1 and my mail server is a virtual machine on ESX host.
