Name

msys.validate.opendkim.get_sig_selector — Fetch the selector associated with a DKIM signature

Synopsis

msys.validate.opendkim.get_sig_selector(dkim_sig)

dkim_sig: userdata, DKIM_SIGINFO type

Description

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

This function requires the opendkim module. It fetches the selector from a DKIM_SIGINFO object. 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 the selector used and the DKIM status (DKIM_STAT). DKIM_STAT 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');.
