Set SMTP mail sending server for Sharepoint (use relay server)

SharePoint often requires email notifications. If the enterprise does not have an Exchange mailbox, you can deploy a simple email SMTP service on the moss server. The configuration method is as follows:
1. Use "Add/Delete" to add an IIS component, SMTP component.
2. Right-click "my computer"-"manage"-expand the tree structure of all IIS, and you will find that a default SMTP is installed, as shown in:
if you do not see "Default SMTP virtual server", right-click "Internet Information Service Manager"-"New"-"SMTP virtual server ", then, refer to step 4.
3. Click "Domain" on the left. Some fields may be listed in the window on the right. If yes, delete all fields. Then right-click "Domain" and select "new"-"domain ", select "local" (this option may be " Local " or skip to Step 4 without your choice)
PS: If you want to use the POP3 mailbox service, do not delete the original domain. just create a new domain on the POP3 management interface. SMTP automatically creates a "Custom" domain. However, this "Custom" SMTP domain cannot use moss email to pass in the service.
4. A dialog box is displayed:
enter the domain name, which must be the domain name of the mailbox on the Internet, or the part after the @ you sent the email.
5. Right-click "SMTP virtual server" and select "properties ", here, "access"-"relay restrictions" and "pass"-"advanced" Settings (the domain name is set to your own domain name, PS: Fully Qualified Domain Name, I used the local prefix, you can also skip this step. The DNS check is successful.)

How to test your SMTP server:

In the command line, enter Telnet <local IP address> 25
An SMTP terminal command will appear,
Enter helo under the big Yu sign (greeting)
Enter mail from: Administrator @ your domain name (set the sender)
If it is not OK, enter it again.
Input: rcpt to: name@email.com (set sender)
If it is not OK, re-enter.
Input: Data (start to write content)
Enter <press enter>. <press enter> (Press ENTER + English + press Enter)
If you are prompted, It will be OK if you have joined the mail queue!
How to Set in Moss:

Outgoing email: During the moss operation, set "outgoing email", fill in the domain name of the local machine, and the sender will be OK.
Input: refer to the following article:

If exchange is not integrated into enterprise applications, is there a way to implement the email import function of moss or WSS?
Someone in my previous SMTP chapter said that I only wrote half of it and asked how to configure it, because the article mentioned configuring SMTP, many people ask if POP3 needs to be configured for the email input function, which is not necessary. If you want to use the simple mailbox function to allow customers to send and receive emails through outlook, you can configure POP3. However, if you only want to implement SharePoint Email Transfer, you do not need to use POP3.
If you configure SMTP in my way, you can implement the input function by making a few simple settings.
Find "incoming email" in "Management Center"

Set as follows:

In fact, it is important to set the domain name and directory:

After setting it, moss or WSS will monitor this directory. Once an email is sent in, the batch processing of the incoming mail will be performed.
You can refer to the following settings in the file Library:


The name entered here is not used before. It cannot conflict with the user name.

It's easy!
