Hi,
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 195.39.55.10, sender <apache<_a.t_>forum.kerio.com> 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.

Regards

Andy Lowe

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 58.9.15.187, sender <ernesto1<_a.t_>galileo.com> 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 61.237.236.113, sender <ac_salev_ideo<_a.t_>jeiofe.info> rejected: sender domain does not exist

With the galileo.com 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
