Postfix with optimization

Hey Guys, Good day. I've configured postfix in ubuntu os. I can send 5k to 10k emails per day. I get some good open rate and response. But now I want to send 50k emails per day.

When I send more than 10k mails, It gets struck and mails are not sending.

As i research in net, some experts are suggested to optimize the server. Can you please help me with that.

Thanks

  • as this is a marketing forum I think you won't get your answers here. Better try something like serverfault.

    about your problem when you say get stuck ... what do you mean exactly?

    your RAM could be maxed out because of settings in mysql or apache or both
    or you could have reached other limits.
    you need to look into all your error logs.

    i don't know about ubuntu but in centos logs are in var directory.
    first look through postfix logs
    then mysql logs
    apache logs

    use something like htop (this is centos again, likely there is something similar in ubuntu)
    to see which process is using which ressources

    this should give you a start. as for the rest as I said better go to a server admin forum

    • I suggest that you do this, first. See what the exact problem is. I also believe that there should be a healthy interval in between email blasts, so as not to slow everything down, especially if you're not planning on paying extra for optimization. -Micah
  • Kindly check following URL and make the necessary changes as per your requirement, keep try to change the settings with new values and check server performance until you satisfied with new limits.
