I send an email on saturday to the same mail without problems (my domain is in SERVER20)

Today i give this message:
unrouteable mail domain "telefonica.net"

I have the same problem with other domains

I have been sent an email from another domain/server and it has not arrived to me.
I?M LOSSING MAILS



P.D. Sorry for my bad english.

i see alot of this also.
One of my clients uses text messaging to dispatch their repairmen.

they send about 50 short emails a day to their NEXTEL emails.

I get about 4-5 a week that bounce back saying the same thing.
unrouteable mail domain

I wrote support about this and they said that nextel.com was
not a valid domain
and thats why the messages were bouncing !!!!!!!

I love this Hosting......

Please Solve it

Hello.

Please change your DNS records to

ns8.hostony.net
ns2.hostony.com


Best regards, Slavik

I have this ones:

DNS#1: NS1.HOSTONY.COM
DNS#2: NS2.HOSTONY.COM
DNS#3: NS8.HOSTONY.COM
DNS#4: NS8.HOSTONY.NET


I change it for:

DNS#1: NS8.HOSTONY.NET
DNS#2: NS2.HOSTONY.COM
DNS#3: NS8.HOSTONY.COM
DNS#4: NS1.HOSTONY.COM

The problem's still standing.

I think it's your problem. If I used to work correctly in the past, and if I did not changed anything. CAN YOU EXPLAIN ME WHY CAN?T SEND/RECEIVED mails to other domains????

Please Solve it, as soon as possible.

yes, my clients have detected problems with sending mails the last few days too.
