为什么邮箱只能接收邮件而不能发送邮件？
由于服务器拒绝接受发件人的电子邮件地址，这封邮件无法发送。发件人的电子邮件地址是“”。 主题 '', 帐户: 'pop.21cn.net', 服务器: 'SMTP.21cn.net', 协议: SMTP, 服务器响应: '553 From &&, message blocked, you are no...
我有更好的答案
1 选择菜单的工具（T）--〉账号（A），在出现的窗口中选中“邮件” 属性页。选中您要设置的账号，再点击右侧的“属性”按钮。在出现的窗口中选择“常规”属性页。您可以看到的界面如图所示。 这里的“电子邮件地址（M）”最好与“服务器”属性页上的外发邮件服务器地址一致。即它们需要是同一个邮件服务器提供商提供的。因为有些外发邮件服务器会检查您的“电子邮件地址”，如果发现不一致，将拒绝发送。 2有些外发邮件服务器需要身份验证。具体设置步骤如下。选择菜单的工具（T）--〉账号（A），在出现的窗口中选中“邮件” 属性页。选中您要设置的账号，再点击右侧的“属性”按钮。在出现的窗口中选择“服务器”属性页，您可以看到的界面如图所示。 选中“我的服务器要求身份验证（V）”，再点击“设置（E）”，您可以看到如下窗口: 选择“使用与接收邮件服务器相同的设置（U）”或“登录方式（O）”并输入账号名与密码

没装SMTP（简单邮件传输协议），或者SMTP有问题。

Sent email in Outlook.com comes back "delivery failed"
Applies To:
Outlook.com
Delivery failures, or emails that bounce or come back as undeliverable, can happen for several reasons. When you send an email and receive a delivery failure message, there could be several reasons. We've listed the most common error messages below, along with suggested resolutions.
Temporary errors
Temporary error messages can include the following.
Can't connect to remote server/message expired
No adequate servers
Connection timed out
Resources temporarily unavailable
Out of memory
These types of errors should fix themselves over time. If your error message says that the recipient's email provider will keep trying to deliver your message, you don't need to take any further action. Otherwise, wait a short time and then resend the message.
Undeliverable
If you receive an error that a message is undeliverable, this could be due to the sending server trying to deliver the message but the action didn't complete before the message expired. This error typically indicates a problem on the receiving server.
Make sure the recipient address is valid. Reduce the number of recipients in the message. If you received this error when sending a message using Outlook or another email app, try using
to send the message instead.
Mailbox not found, Invalid mailbox, or User unknown
If you receive one of these messages, the address you used doesn't exist. This could be because the recipient's address has changed or the recipient's email account has moved.
Check the recipient's email address for typos. If you have another way to get in touch with the recipient, see if they have a new email address.
Mailbox unavailable
Often, this error message has the same cause as the Mailbox not found message. However, occasionally there's a problem with the recipient's email account that will resolve itself over time.
Wait a short time and try to send your message again. If that fails, check the recipient's email address for typos. If you have another way to get in touch with the recipient, see if they have a new email address.
Mailbox full or Quota exceeded
This message means that the recipient has too many messages in their inbox. Many email systems prevent users from receiving any new mail until they reduce their mailbox size.
If you have another way to contact the recipient, let them know that their mailbox is full.
Host unknown or Domain lookup failed
If you receive one of these messages, the domain for the recipient's email address doesn't exist. If their email address is , the domain is example.com.
Check the recipient's email address for typos. Ensure you have the current address and that their email service provider hasn't made a change to their domain name.
Message too large
Most email service providers impose a limit on the size of messages their users can send or receive. Your message is too large for the recipient's email server.
Instead of sending large attachments via email,
and send the recipient a link.
Errors that include "blocked" or "listed in" and references to sites like "spamcop," "dynablock," "blackhole," or "spamhaus"
These terms are used when your message has been intentionally blocked by a spam or blacklist filter on the recipient's email server. The recipients server believes that the mail server or mail account that you're using is a source of spam.
You can contact the support team for the recipient's email provider and request to have your account or domain unblocked.
