[PATCH] libspf2/spf_request.c: Fix handling of email addresses in query_rcptto().
|
|
From: Florian Forster <ff [at] octo>
The function SPF_request_query_rcptto() checks whether the "rcpt_to"
string argument contains the "@" character. If so, everything before the
at-sign is stripped. However, the at-sign itself left in front of the
string, so that the generated SPF record reads:
v=spf1 mx:@example.com
The actual checking code then tries to resolve "@example.com" rather than
"example.com", fails and returns "neutral" even when it should return
"pass".
This patch adds the missing `rcpt_to_dom++` so the at-sign is stripped,
too.
