[root@qmail ~]#
In addition I have changed out DNS programs on the mail server to
try to help i.e.
caching-nameserver
pdns-recursor
djbdns (rbldnsd)
Currently, I have DNS lookups pointed to a Windows DNS server with the
same issue. Doing a dig or nslookup on the mx records shows a valid
mx record.
Does anyone have an idea as to the problem?
Thanks,
Ed
