Here's a quick rundown on the settings that differ from other services defaults: maxproc The maximum number of concurrent Postfix amavis-service processes has been limited to 2 (default: default_process_limit = 100). This value reflects the default of 2 amavisd-daemon children processes and is a good setting to start from. The value may be raised later, when the system works stable and still can take a higher load. It should not exceed the number of simultaneous amavisd child processes. lmtp_data_done_timeout Setting lmtp_data_done_timeout to 1200 (seconds) doubles the default time span a regular Postfix client waits after message delivery for the server to reply DONE to claim successful delivery.
