${verify}

Result of cert verification V8.11 and above

When a connection is made or received and STARTTLS is negotiated, sendmail updates the value of several macros, among which is this ${verify} macro.

This ${verify} macro stores a text word that describes the result of verification of the presented certificate. Those possible text words are shown in Table 21-10.

Table 21-10. Possible values for ${verify}

Word

Description

FAIL

A certificate was presented but could not be verified

NONE

STARTTLS has not been performed

NOT

No certificate was requested

NO

No certificate was presented

OK

The verification was successful

PROTOCOL

A protocol error occurred

SOFTWARE

The STARTTLS handshake failed (message will be queued)

TEMP

There was a temporary error

The ${verify} macro is used in the standard configuration file as part of the definition of the Received: header: If ${tls_version} has a value, the following is included in the Received: header's text:

(version=${tls_version} cipher=${cipher} bits=${cipher_bits} verify=${verify})

If ${tls_version} lacks a value, the preceding text is not included, meaning a STARTTLS connection was not used.

${verify} is transient. If it is defined in the configuration file or in the command line, that definition is ignored by sendmail. Note that a $& prefix is necessary when you reference this macro in rules (that is, use $&{verify}, not ${verify}).
