> How can I increase mail sending speed in postfix Find out where your bottleneck is and attack it. I'm sorry, but it's impossible to give a more specific answer without additional details. Usually Postfix performance is bound by the I/O performance of the machine, so getting a faster disk, a faster controller, or switching to SSD for the queue are often good ways of increasing the throughput (provided you don't have any long hanging fruit like unnecessary content filters). Start by analyzing where a message spends its time by looking at the logging. I don't know if it's the canonical source of documentation of this piece of logging, but http://www.postfix.org/postconf.5.html#delay_logging_resolution_limit contains what you need to know.
