Hi all,

We are using the option 'Block if senders mail domain was not found in DNS' and looking through the security log it does bin some bad mail however it is also getting rid of some good mail:
[09/Nov/2009 10:58:14] Message from IP address 109.123.xxx.xxx, sender <"info<_a.t_>domain.com"<_a.t_>mail.uk2.net> rejected: sender domain does not exist

info<_a.t_>domain.com is obviously the senders address and <_a.t_>mail.uk2.net is the company they use for email. Both domains are good.
Can I assume Kerio is trying to do a DNS lookup on domain.com"<_a.t_>mail.uk2.net and failing?

Other than switching off the DNS check, is there a way around this?
