    Default Problems with message size...

    We have a zimbra email server setup and have some clients that are needing to send some larger files as attachments. Unfortunately, even after following the instructions in the wiki (Configuring maxmessagesize - Zimbra :: Wiki) I am unable to send large messages.

    I am attaching a 10 MB file to the email message and sending it. The error I get back is:

    <>: message size 14011600 exceeds size limit 3072000 of server[]
    I understand that the message is too big for the limit on the server. However, I have set the limit to 104857600 for both zimbraFileUploadMaxSize and zimbraMtaMaxMessageSize.

    Any idea what might be causing this problem?

    not sure if it helps, but did you restart zimbra service after change these values?

    Well, I actually found the problem and it wasn't with Zimbra, though I did make sure to restart Zimbra when setting these.

    Turns our the stupid firewall was limiting attachments to 3 MB. Bumped it up and things started working.
