msys.validate.opendkim.get_sig_hdrsigned

msys.validate.opendkim.get_sig_hdrsigned — Determine whether a given header was signed

msys.validate.opendkim.get_sig_hdrsigned(dkim_sig, header_name)

**Configuration Change. ** This function is available as of version 3.6.

This function requires the opendkim module. This function determines whether a header has been signed. Use msys.validate.opendkim.get_num_sigs and msys.validate.opendkim.get_sig to get a DKIM_SIGINFO object to pass to this function. For a description of the DKIM_SIGINFO object see DKIM_DSIGINFO.

This function returns a Boolean indicating whether the specified header has been signed. It also returns the DKIM status (DKIM_STAT) which can be any one of the following values:

• DKIM_STAT_OK – successful completion

• DKIM_STAT_BADSIG – signature did not match headers and body

• DKIM_STAT_NOSIG – no signature present

• DKIM_STAT_NOKEY – no key available for verifying

• DKIM_STAT_CANTVRFY – can't get key for verifying

• DKIM_STAT_SYNTAX – message is not in valid syntax

• DKIM_STAT_NORESOURCE – resource unavailable

• DKIM_STAT_INTERNAL – internal error

• DKIM_STAT_REVOKED – signing key revoked

• DKIM_STAT_INVALID – invalid parameter(s)

• DKIM_STAT_NOTIMPLEMENT – function not implemented

• DKIM_STAT_KEYFAIL – key retrieval failed (try again later)

• DKIM_STAT_CBREJECT – callback requested message rejection

• DKIM_STAT_CBTRYAGAIN – callback can't complete (try again later)

• DKIM_STAT_CBERROR – unspecified callback error

Enable this function with the statement require('msys.validate.opendkim');.
