    There's threads in the forums with answers to that question. In any case, you don't seem to have asked a question nor provided any information about your configuration.

    In future, do not add your post to a thread that's over two years old.
    Regards

    Ok, you are kind, but this is the first post in the forum searching about "sizing" and I don't understand why you leave the thread open if you dislike someone could ask about an answer.

    I've seen two people questions and informations but I've not found some support consideration.

    So this is why I've posted that message with that question.
    About the info I could pass: I'm a VMWare Partner and I'm studying all the cases not listed in the official Zimbra documentation. This is because the customers pay attenction to some detail like the sizing one.

    My customers are big, small and medium entities so I need a wide vision about the Zimbra sizing possibilities. I can't give you only one environment information, but it's quite good to me to find many experiences and make a general consideration about this real problem.

    Thank you anyway and regards
    Dario
