It does I believe need some sort of whitelisting capability. We have lots of non-SMTP compliant devices on the inside of our network that are getting rejected for Invalid HELOs. (Printers, Dell RACs, etc, etc). Ideally it should respect the Sendmail Access DB. As of this point, we've had to turn it off unfortunately.
Thanks

The sender address verification sends an HELO *before* the receiving server emits its SMTP banner. Thus, the probe (or the whole server) gets classified as "earlytalker" and (in my case) gets disconnected immediately. The verification probes must adhere to the SMTP protocol, otherwise they're worthless because they're generating false negatives.

RFC-2821 states that email addresses are case insensitive except for the local part, but smf-sav.c always converts the whole email address to lowercase (to check its whitelist). So when smf-sav tries to confirm the email address with the domain's SMTP server, it does not give back what sendmail got. This breaks email from any domain that uses an IronPort Email Security appliance. Attached is...

ossec-hids analyzes log entries and can take actions to block the offender at the firewall. To do this it is valuable to have the message source ip address in the log line output (as opposed to just the FQDN).
This patch just adds context->addr to the syslog output of smf-zombie.c; apply and make install.

The SPF-Received: header is better added to the top of the message, above the Received: header of the sending system. This is done using smfi_insheader() in place of smfi_addheader()
