    How work postfix, exim4 and courier together?

    I would like to understand what this demons are doing. In the mail logfiles I found a notice:
    I now that I can edit the mailbox_size_limit in postfix but not the message_size_limit. It must came from exim4. What is exim4 doing and why postfix doesn't do the exim4 tasks? What have the courier demon to do?

    Both Postfix and Exim are mailservers. If you have Postfix installed, then Exim is not installed, and if Exim is installed, then Postfix isn't.
    Courier is the POP3/IMAP server (that you use to fetch mails from the server).
    I have answered to your message_size_limit problem in your other thread. :)

    Thanks for resolving the message_size_limit problem :)

    When I was searching for message_size_limit if found that line:
    That seem to me that exim and postfix are installed. Is'nt it?

    It might be, but i dont think so. I guess there are only the config files from a prevoius exim installation left.

    if you run:

    ntstat -tap

    Is exim or postfix listed as smtp daemon?
