Why can't I receive messages from imail and how to solve them?

 
 

The Enterprise post office set in Imail can only send emails, but cannot receive emails from outside. The mutual acceptance test between mailboxes in this domain finds no problem. Is this a problem set in Imail? There are generally the following reasons:
1. Your "IP address connected to port 25" is blocked in the IDC room (because the IDC room is large to prevent mass spam emails
This can be done in some data centers) or your own firewall limits "port 25 for external connections.
You can use the following method to test whether your "IP address port 25" is blocked.
Click Start Menu
Select Run
Enter telnet smtp.163.com 25
The following message is displayed: "220 163.com Anti-spam GT
Coremail System (163com [20050206]) ". If no English prompt is displayed
Information indicates that port 25 is blocked by the data center. In this case, you can only connect
Data center processing .)
2. the dns of your email software is not properly set.
If the dns server in imail is not set, you can refer to the following methods to set it:
Click Start Menu
Select Imail-IMail Administrator,
Open the imail management interface,
Click localhost
Select serviecs
Select SMTP
Select "Domina Name address"
Enter the dns ip address (multiple IP addresses can be separated by spaces. The dns ip address must be exactly the same as the dns ip address set in TCP/IP in the NIC attribute, many users write the wrong IP address, causing the mail to fail ). Click "application" to complete the settings.
3. It is caused by an incorrect email address.
If you use the admin user name of winwebmail, you cannot send emails,
You should bind a domain name in the user zone before sending an email.
4. It may be caused by anti-virus software.
For example, Mcafee and rising may cause an issue where emails cannot be sent. You can disable anti-virus software and then
Restart the mailbox software to see if it is caused by anti-virus software.
5. imail is not cracked or the smtp service of imail is not started.
If you have checked that the smtp service of imail has been started, you can run netstat-an in dos
Step check. Normally, we should see "port 25 in listening". If no port 25 in
"Set the listener according to the following steps:
Click Start Menu
Select Imail-IMail Administrator,
Open the imail management interface,
Click localhost
Select serviecs
Select SMTP
Select "Advanced )"
Check "enable listen on IPs"
Click "application" to complete the settings.
Restart the smtp service and check whether port 25 is listening.
We can see that port 25 is listening. This is probably because imail has not been cracked successfully.
In this case, only the system can be reinstalled to restore normal.
