How can I modify the Access Control List (ACL) for the IMSS scanner?

You can modify the following settings in imss.ini.

Add the target IP address to the parameter smtp_allow_client_ip.
Alternatively, disable ACL check by setting open_to_all_connections=yes.
To ensure that other computers are able to connect to the scanner, insert the target IP addresses in the parameter proxy_smtp_server_ip.

For more details, refer to the comments in imss.ini.
