Email route problem

[Timgles]

Hello everybody,
I have a small problem with my customer email.
This customer's website is in my server, emails are purchased elsewhere and the nameserver services are provided by third party.

I have done normally cPanel - account for this customer. But if my server to send email to this customer, it will not ever go through. Not another e-mail account (which is my server) or the website feedback form.

What should I do that I get emails to work in my server. This customer does not want to move the nameservers or emails in my server.

Best Regards, Timgles

remote the domain from /etc/localdomains
add the domain to /etc/remotedomains

all fixed

Not working....
There will be only the sender and "Mail delivery failed: returning message to sender"

"The mail server could not deliver mail to test@notshow.com. The account or
domain may not exist, they may be blacklisted, or missing the proper dns
entries."

Are there any other ideas?

Make sure you don't have a local DNS zone file for their domain setup
or the server will use those settings instead of the authoritative DNS servers
for the domain and your zone files will superceed the real ones when sending
mail to the client's addresses from your own server irregardless of the
/etc/localdomains and /etc/remotedomains.

Personally, my experience with clients that insistent on using their own DNS,
my general consensus is well something that couldn't be said in public forum.
They generally come around or realize the hard way why that rule is in force
and in what few instances there have been over the years, come crawling back
again pretty quickly when they figure out the errors of their ways. Bottom line
is I wouldn't be that flexible but my first paragraph above will probably clue you
into the issue with this particular case.
