[Resolved] "No MX records found for" domains


Recommended Posts

Hi,

I'm trying to add a new MailHost, but I get errors "No MX records found."

MX records exist for the domain:

# Host-t mx ciacho.pl

ciacho.pl mail is handled by 20 mx2.witrynka.pl.

ciacho.pl mail is handled by 10 smtp.ciacho.pl.

# Host-t mx ciacho.art.pl

ciacho.art.pl mail is handled by 5 alt1.aspmx.l.google.com.

ciacho.art.pl mail is handled by 10 alt2.aspmx.l.google.com.

ciacho.art.pl mail is handled by 30 aspmx2.googlemail.com.

ciacho.art.pl mail is handled by 50 aspmx3.googlemail.com.

ciacho.art.pl mail is handled by 1 aspmx.l.google.com.

ciacho.pl SOA (Zone of Authority) ....

Point being that the MailHost Configuration code may include a scan for the text string highlighted in red above and once seen, drops out. I don't recall seeing this issue being brought up 'here' before.

Also noting that this same 'problem' doesn't appear in the second Domain listed, primarily because it doesn't have the ns3 server in the data record/file.

Feedback on just what the actual issue turns out to be sure would be nice.

Fixed configuration (removed ns3.witrynka.pl NS record), but the problem still occurs. For example, I have a similar problem for the domain and there ciacho.pl NS records are accurate.

Unfortunately, I don't have anything for you.

I tried and tried, but SpamCop never did find an MX for the domain. I didn't have any trouble finding an MX with my personal tools. All very strange.

I developed enough information about the hosts that I was able to create registrations and put them on his account, so the user is good to go, but the MX mystery remains.

Thanks. As far as the Topic/query goes, tagged as Resolved.

Can anyone confirm the DNS records are good? The 1 sec TTL seems strange to me. Not affecting anything here but what is that SPF record about? (The first 3 IP addresses?). All magic to me I'm afraid, just asking ...

I get the same as you. The TTL makes it look pretty odd indeed; these lookups would effectively never be cached. The two MX hosts are also on the list for SPF, which seems reasonable for a small operation. The other three addresses show up in Poland, also to be expected here. The SPF (TXT) record seems to say "allow any of these five hosts (but no others) to deliver mail claiming to be from ciacho.com"

Thanks Rick, I struggle with that stuff. :blush: I can't help feeling there would not have to be much wrong with the SC MX lookup routine for it to struggle with uncached entries.

I don't specifically understand the Telnet-net and Inetia.pl servers being in the SPF record, but they must be part of the routing I guess, or they wouldn't be there. That may also be part of SC's difficulty though it seems Don may have been alerted to some other difficulty. I'm faintly amazed that the internet works at all. Maybe I'm imagining it all. Are you other guys really there? Can you prove it? :D
