Hey,
We currently use ASL 4 with the SMTP proxying services. The last few weeks I have noticed that we have been unable to send to certain domains. Below is the returned message code as well as the host we are trying to send to DNS records.
Error Message
It appears that the DNS operator for XXXXXXXXX.com
has installed an invalid MX record with an IP address
instead of a domain name on the right hand side.
DNS Entry
XXXXXX.com internet address = XXX.XXX.XXX.XXX
XXXXXX.com nameserver = ns1.XXXXX.net
XXXXXX.com nameserver = ns2.XXXXX.net
XXXXXX.com
primary name server = dnsmaster1.XXXXXX.net
responsible mail addr = hostmaster.XXXXXX.net
serial = 2004011001
refresh = 10800 (3 hours)
retry = 1800 (30 mins)
expire = 604800 (7 days)
default TTL = 300 (5 mins)
XXXXXXXX.com MX preference = 10, mail exchanger = XXX.XXX.XXX.XXX
ns1.XXXXX.net internet address = XXX.XXX.XXX.XXX
ns2.XXXXX.net internet address = XXX.XXX.XXX.XXX
As you can see their MX host's IP is associated with the MX record rather than a DNS entry. Is it possible to allow the ASL SMTP proxy to send to this host even though their MX record is less than Ideal?
Thanks,
Chad Nelson
