  • Delete and clear POSTFIX queue in one line

    Oftentimes, you may need to just delete all messages in queue (for example, when your script has gone mad and generated too many messages to handle, once you’ve stopped postfix). It’s quite simple, really: (more…)

  • Postfix maximum individual mail size and mailbox size

    If you’re getting the "5.3.4 Messag exceeds fixed limit” error, check on the default vs set values in your /etc/postfix/main.cf using
    postconf -d (for the default)
    and
    postconf -n (for the values you have set manually in the main.cf)
    Default for message_size_limit (maximum size per mail) is 10240000 (bytes, ie approx 10MB)

    Up this to your desired value, eg 30MB by setting
    postconf -e "message_size_limit = 30720000"
    specifiying the size in bytes.
    You can reset the maximum mailbox size using the same method (below just resets to the default value)
    postconf -e "virtual_mailbox_limit = 51200000"

    But you knew that already!
