I can't seem to send emails to certain domains. This problem was address before, but seems to be slightly different from mine.
Here's the lowdown:
I'm using Bynari Insight Server, and the mail queue error message for the failed emails says:
lost connection with mail-fwd.sbc-webhosting.co
237.169] while sending HELO
So I tried the whole nslookup routine that subsoniq laid out, and here what I typed and got:
Default Server: pdc.mixergroup.net
> set type=mx
m MX preference = 50, mail exchanger = mail-fwd.sbc-webhosting.co
sbc-webhosting.com nameserver = ns26b.sbc-webhosting.com
sbc-webhosting.com nameserver = ns1.sbcidc.com
sbc-webhosting.com nameserver = ns2.sbcidc.com
sbc-webhosting.com nameserver = ns26a.sbc-webhosting.com
m internet address = 18.104.22.168
m internet address = 22.214.171.124
m internet address = 126.96.36.199
m internet address = 188.8.131.52
z:\>telnet ns26b.sbc-webhosting.com 25
Connecting To ns26b.sbc-webhosting.com..
.Could not open a connection to host on port 25 : Connection failed
And that's where I'm stuck. I don't know if our DNS lookup is screwy, or even how to fix it. Any help or direction would be greatly appreciated.
