Kerio Mailserver seems to be blocking my activation email from this forum site, if 'Block if sender's mail domain was not found in DNS' is ticked I get the follow error in the security log 'Message from IP address, sender <apache<_a.t_>> temporarily rejected: sender domain does not resolve'.
Is there anyway to keep this option turned on and add that domain or email address so Kerio Mailserver allows mail through.

I'm suddenly getting a lot of these as well and it's very annoying. It's started since I upgraded to 6.5

It's happening with domains I know for a fact resolve. I have monitored the logs and run a lookup against a domain as soon as it appears and it resolves. I check against several dns servers.

It's different from domains which are bogus because those do not say "temporarily rejected" but are "rejected" outright as usual.

Here's a problematic one (i.e. the domain DOES resolve):
[20/Mar/2008 06:19:47] Message from IP address, sender <ernesto1<_a.t_>> temporarily rejected: sender domain does not resolve

Here's one I'd expect to fail:
[20/Mar/2008 06:12:14] Message from IP address, sender <ac_salev_ideo<_a.t_>> rejected: sender domain does not exist

With the issue, this domain has been registered since 1994 and is registered until 2010. They have host A records for their root domain and also have 4 MX records.

This is very strange
