Email 信箱容量與限制說明(Email Account Storage and Limitations)

信箱容量限制(Mailbox Storage Limits)

教職員：每個帳戶預設信箱容量為 15GB。
學生：每個帳戶預設信箱容量為 1GB。
當信箱接近容量上限時，系統會自動發送警告通知，提醒您清理郵件。如果信箱容量超過限制，將無法接收新郵件，直到釋放出足夠的空間為止。

Staff: Each account has a default mailbox storage of 15GB.
Students: Each account has a default mailbox storage of 1GB.
When your mailbox is nearing its storage limit, the system will automatically send a warning notification, reminding you to clean up emails. If the mailbox exceeds its storage limit, new emails cannot be received until enough space is freed.

請注意，上述限制是本校系統的標準，信件能否成功寄達仍取決於對方系統的限制以及所使用的郵件軟體。建議傳送大檔案時，使用雲端儲存空間分享連結來替代直接傳送附件。

以下是常見郵件系統的附件大小限制：Gmail：25MB　，Yahoo：25MB　，Outlook：20MB

Maximum incoming email size: 40MB

Please note that the above limitations are standard for our system. Whether an email is successfully delivered depends on the recipient's system limitations and the email software used. For large files, it's recommended to use cloud storage links instead of sending attachments directly. Below are attachment size limits for common email services: Gmail: 25MB, Yahoo: 25MB, Outlook: 20MB.

單封信件收件者上限(Maximum Number of Recipients per Email)

教職員：每封信件最多 150 位收件者。

學生：每封信件最多 100 位收件者。

為避免郵件被判定為垃圾郵件，大量發送信件時建議分批寄送。某些郵件系統（例如 Gmail）會偵測重複內容或大量發送的郵件，可能會將其標記為垃圾郵件而拒收。
 

Staff: Up to 150 recipients per email.
Students: Up to 100 recipients per email.
To avoid emails being marked as spam, it is recommended to send emails in batches for mass communication. Some email systems (e.g., Gmail) may detect duplicate content or mass-sent emails and flag them as spam, potentially rejecting them.

大量寄信限制(Mass Email Sending Limits)

教職員：每小時最多可發送 450 封郵件。

學生：每小時最多可發送 250 封郵件。

大量寄送信件時，請注意控制發送量，以避免被對方系統封鎖或判定為垃圾郵件。

Staff: Up to 450 emails can be sent per hour.
Students: Up to 250 emails can be sent per hour.
When sending a large number of emails, be mindful of the volume to avoid being blocked or marked as spam by the recipient’s system.
