We recommend you choose the option to limit the file size of emails to send/receive via WebMail.

By limiting the size of emails, you can avoid the risk of slowing down the performance of Office 4.

The default setting is to limit the file size. However, it will be effective only if your POP3 server complies with UIDL commands.

If you limit the incoming/outgoing email size, the following conditions will exist:

• You cannot send email over 256KB from WebMail.
• You cannot receive emails over 512KB from WebMail.

To set a limitation on the size of emails that you receive or send, follow these steps:

1. From the Portal Page, choose WebMail > Setting.

   If you are not already logged in as Admin, enter your admin password when prompted.

   Select Incoming/Outgoing Email Size Setting.

2. Check the Limit the File Size of Emails to send/receive via Cybozu WebMail box.

3. When done, click Save.

4. Even if you do limit email size, the most emails you can receive at one time is 100 emails or up to 5MB. If you receive more than that, the following message will be displayed:

   "You still have emails to receive in the mail server. Please continue to click the Check New Emails button."

   However, the size of the first email may exceed 5MB and you will still be able to receive it. The size of an email is the result of the Mail Header + Mail Text + Attachment Files to be encoded (BASE64). In this instance, click Check New Emails and continue receiving emails.
