Support for smtp_send_xforward_command parameter in InterScan Messaging Security Virtual Appliance (IMSVA) 9.1

- Updated:
- 24 Nov 2016
- Product/Version:
- InterScan Messaging Security Virtual Appliance 9.1
- Platform:
- CentOS 6 64-bit

Summary

By default, Postfix sets smtp_send_xforward_command value to "no". If the value is changed to "yes", Postfix will try to forward the original client name and IP address instead of the SMTP proxy IP through the after-filter smtpd process, so that filtered mail is logged with the real client name IP address.

This might cause Postfix to get a wrong source IP and cause IP Filtering not to function properly.

Details

It is suggested not to change the default setting for this parameter.
