IMAP4 Service Configuration

IMAP4 Service enables the user to receive email from mailbox to local email client based on IMAP4 protocol.

General Settings

IP Address

By default, SMTP/POP3/IMAP4/Remote Object Call services listen on all IP addresses of the server. In most case, you do not have to change this setting. To make the service to listen on specified IP address, you can change the IP Address field like this:

If you only need this service listen on 192.168.0.1,
then just input 192.168.0.1 to IP address.

If you want to bind multiple addresses in this service.

192.168.0.1
192.168.0.2
192.168.0.3
Then input: 192.168.0.1, 192.168.0.2, 192.168.0.3

If you want to bind multiple addresses with different port

192.168.0.1 with 143 port
192.168.0.2 with 143 port
192.168.0.3 with 143 port
Then input: 192.168.0.1 143, 192.168.0.2 143, 192.168.0.3 143

• Only the IP addresses in the list. Only the IP addresses is matched to an item in the list, the user can connect to the IMAP4 server.

• All except the IP addresses in the list. If the IP addresses is matched to an item in the list, the user cannot connect to the IMAP4 server. (This option is recommended)

Wildcard character (*) or CDIR syntax are available to identify a group of IP addresses. E.g. 192.168.0.* or 202.*. CDIR syntax: E.g. 192.168.0.1/16 represents a group IP addresses from 192.168.0.1~192.168.255.255.
