Hello, I have a run expansion using a tainted variable:
condition = ${run{/usr/bin/spfquery.mail-spf-perl \ --ip $sender_host_address \ --scope mfrom \ --identity $sender_address} \ {no}{${if eq {$runrc}{1}{yes}{no}}}} Is this usage of $sender_address safe? And if not, what would I do to make it safe? Thanks, Dominic. -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-users-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
