Hi
Some puzzling situation:
fasfnt.com requires customer who want to cancel their service, to
contact them by email.
fasfnt.com mail is handled by 0 web242.dnchosting.com.
This server is rejecting emails to the domain fasfnt.com, according to
directnic who operates that email service, because the domain
fasfnt.com is not configured and most likely the domain owner published
a wrong MX entry via DNS.
According to fasfnt.com they receive emails sent to [email protected]
so according to them the MX is correct and the email service working as
expected. Thus, if an email can not be delivered, the sender ISP has to
solve the issue.
So, do their DNS return different MX according to the geolocation of
the lookup?
I get:
# host -t mx fasfnt.com
fasfnt.com mail is handled by 0 web242.dnchosting.com.
# host web242.dnchosting.com.
web242.dnchosting.com has address 192.64.150.242
web242.dnchosting.com has IPv6 address 2602:fc8e:0:688e:150::242
- I am in the UK, using BT as my ISP.
1.1.1.1, 8.8.8.8 and 9.9.9.9 give the same results.
