[exim] "No errors" in $spf_header_comment

[Patrik Peng via Exim-users]

Hi all




In case of failures, we log additional details the following way:

mail_acl:
- - 8< - -
        deny    spf     = permerror

                message = SPF check failed: $spf_result while checking \
                                ${if 
def:sender_address_domain{$sender_address_domain}{$sender_helo_name}}
                log_message = SPF check failed: $spf_result - 
$spf_header_comment

Now there have been a few cases, where a message like this has been logged:

SPF check failed: permerror - ourmxinhost.net: error in processing during 
lookup of domain of example.com: No errors

Notice the "No errors" at the end.




Regards,
Patrik

We're using Exim version 4.98 on FreeBSD and recently switched from perl-based spfd SPF checks to Exim's native one. One known case, where such message is logged is when a domain has multiple TXT RRs containing SPF policies. I'm assuming this is a bug and it would be nice to have further information in such cases to debug these failures.
