DNS lookups



Hi there,

zmailer has a Problem with DNS lookups. If a host has
no MX entry, but a valid IP Adress then the SPAM filter
will not accept mails (Access denied due to excessive spamming ...).
Or better say if the nameserver doesn't offer the MX record.
I think zmailer fills a record that gets empty if it asks for
the MX record so the IP address is lost and the mail receipt is beeing
refused.
Then the error message could get better. I had the case
with owner-softverf@lal.cs.byu.edu, where the maintainer was shocked
to hear that his domain is ostensible a SPAM domain, but just
the DNS lookup failed !

Greets, Sven
