Environment

GWAVA4.5 build 125 (and prior builds with SMTP scanner) SMTP scanner

Situation

I am getting the message (550 invalid HELO string (IPV4 0.0.0.0)) when sending mail through GWAVA.

Resolution


This message will usually not be for all outgoing mail being scanned by GWAVA.  Some receiving mail servers will not accept the HELO command (start of email conversation), if the IPV4 address shows as 0.0.0.0

To resolve this issue:
1) Open your GWAVA web management console: (<ip_address>:49282).
Go to Server/Scanner Management | Server name | Manage scanners | scanner name | Configure SMTP settings | Mail interface settings
2)  Change the settings.
Near the top of the page you will see TCP/IP bind address (listen address).

By default, this is set to 0.0.0.0 (unless you changed it during the scanner installation).

Change this address to the physical IP address of the GWAVA server.
4) Save changes.
