As we have seen issues in DNS processing actually stops rspamd from
processing a message, which leads to missing tag insertion for example,
we turn on soft reject on task timeout. Behavior is the same as with
greylisting for example, so the mail will be delayed/soft rejected, but
as DNS issues usually are most likely temporarily, it should get delivered
on the second try.
When using a redirect in your SPF record, the web UI validation
failed when your record contained a ipv6 address. In
web/inc/ajax/dns_diagnostics.php the function get_spf_allowed_hosts
is called with the second parameter to be true to expand ipv6
addresses. But when called for redirects, the value was not set to
true, so it defaulted back to false. This caused an unexpanded ipv6
address to be added to the array and the in_array match for ipv6
never matched as it is always called with expand_ipv6.
While looking at the code i noted some messed up in the indention,
which is also "fixed" by this commit.
In #4105 there was a small error that renamed the input name to
input id, so we lost the name and the title name couldn't be
changed anymore. This should fix it.
