You can tune that with options like (adjust values to your needs) these: queue_only_load = 3.0 deliver_queue_load_max = 4.0 queue_run_max = 5 remote_max_parallel = 8 smtp_accept_max = 50 smtp_connect_backlog = 55 smtp_accept_max_nonmail = 20 smtp_accept_max_nonmail_hosts = * smtp_accept_max_per_connection = 40 smtp_accept_max_per_host = 10 smtp_accept_queue = 15 check_spool_space = 768M check_spool_inodes = 10000 message_size_limit = 60M return_size_limit = 4k bounce_return_size_limit = 4k There is a chapter about "Resource control" in the Exim documentation. I even consider setting some of these options as required in any case, to protect the server from beeing overwhelmed. In particular, "queue_only_load" and "deliver_queue_load_max" can help greatly to even out the load by keeping it below your specified maximums when there is a spike and processing them later when the load is lower. I've seen it happening, and it worked great. -- http://en.wikipedia.org/wiki/Posting_style -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
