Фуею с американских ISP

Оригинальный тикет:

Support ticket to be issued to: ISP.com
Support ticket problem definition:

COMPANY company uses hosted server www.COMPANY.com only for sending mails (mostly to addresses on the COMPANY.com domain). We use mail servers of our domain provider, GoDaddy:

host -t mx COMPANY.com
COMPANY.com mail is handled by 10 mail.COMPANY.com.

host -t mx COMPANY.com ns1.uar.net
Using domain server:
Name: ns1.uar.net

COMPANY.com mail is handled by 10 mailstore1.secureserver.net.
СЩЬЗФТН.com mail is handled by 0 smtp.secureserver.net.

However we experience major problems with sending mails from our box hosted on ISP:
[root@www sysconfig]# nslookup mail.COMPANY.com
Server: xxx.xx.170.17
Address: xxx.xx.170.17#53

Name: mail.COMPANY.com
Address: xx.xx.151.248

This makes impossible to deliver mails to COMPANY.com domain from our ISP box.

Can you let us know why information provided by ISP DNS server differs from real information about COMPANY.com domain seen to world? Note: we are sure that settings for COMPANY.com mx servers were not changed recently, and remain at least for 5 months. Can you please fix this issue?

Ответ ISP:

The mail server for the domain COMPANY.com is not resolving to our servers. As they point to smtp.secureserver.net and mailstore1.secureserver.net. we may not able to check your issue with mails.

You will have to contact the providers of your mail server for the ame issue.
Please let us know if you have any further questions .

Уточнение тикета :
I think there's is some confusion here.

Issue occurs only on our ISP server and only on DNS servers that serve queries from this box. To check it, please run host -t mx COMPANY.com using DNS server that our ISP box is using - please note that it is not
yy.yy.18.125#53(yy.yy.18.125) that you were using in your test, but xx.xx.170.17 which was set up by ISP as our DNS server for our COMPANY.com box.

Ответ ISP:

In one of your previous tickets #73484, you have asked to configure your domains in the ISP name servers. So we have configured your domain on our name servers with a default mx record ( since you did not mention any specifications ). But you have not migrated your domains to ISP DNS servers.

What to do?

you have site designed in a dark theme, saying dark background, white font.
By default google toolbar autocomplete cracks html for inputs or selects containg "email" "name" "address" and other buzzwords and changes background to yellow. As a result when visitor fills form, he enters text as white on yellow and can not easy validate his input
What to do?
