如何使用 office 365(Exchange online) 提供裝置或應用程式發送郵件
1.Option 1 (recommended): Authenticate your device or application directly with an Office 365 mailbox, and send mail using SMTP client submission
(此方法需要一個Exchange online授權帳號及發送裝置要支援TLS等協定)
| Device or Application setting | Value |
|---|---|
| Server/smart host | smtp.office365.com |
| Port | Port 587 (recommended) or port 25 |
| TLS/ StartTLS | Enabled |
| Username/email address and password | Enter the sign in credentials of the hosted mailbox being used |
此功能限制:
You can only send from one email address unless your device can store login credentials for multiple Office 365 mailboxes.
Office 365 imposes a limit of 30 messages sent per minute, and a limit of 10,000 recipients per day.
2. Option 2: Send mail directly from your printer or application to Office 365 (direct send)
| Device or application setting | Value |
|---|---|
| Server/smart host | Your MX endpoint, for example, contoso-com.mail.protection.outlook.com |
| Port | Port 25 |
| TLS/StartTLS | Enabled |
| Email address | Any email address for one of your Office 365 accepted domains. This email address does not need to have a mailbox. |
We recommend adding an SPF record to avoid having messages flagged as spam. If you are sending from a static IP address, add it to your SPF record in your domain registrar's DNS settings as follows:
| DNS entry | Value |
|---|---|
| SPF | v=spf1 ip4:<Static IP Address> include:spf.protection.outlook.com ~all |
此功能限制:
-
Direct send cannot be used to deliver email to external recipients, for example, recipients with Yahoo or Gmail addresses.
-
Your messages will be subject to antispam checks.
-
Sent mail might be disrupted if your IP addresses are blocked by a spam list.
-
Office 365 uses throttling policies to protect the performance of the service.
3.Option 3: Configure a connector to send mail using Office 365 SMTP relay
