I bought a domain at a host I use expressly to use for handling family personal email. I then bought a year here and created a couple of email accounts.
I did some setup at NFSN. Following instruction from you - MXRoute - I added resource records a day or so ago as follows:
MX - 10 longhorn.mxrouting.net.horselovers.party.
MX - |20 longhorn-relay.mxrouting.net.horselovers.party.
TXT - |“v=spf1 include:mxlogin.com -all”
CName - longhorn.mxrouting.net.horselovers.party.
CNAME - longhorn.mxrouting.net.horselovers.party.
As things stand now I can successfully go into Webmail and send from these email accounts to email addresses I control. But when I reply to them I get undeliverable email messages back that say-
Unfortunately, your mail was not delivered to the following address: firstname.lastname@example.org: Sorry, I couldn’t find a mail exchanger or IP address. (#5.4.4)
I can successfully send emails to back and forth from and to the email accounts from within the webmail system
Can you point me towards how to get things working?
