I'm using everyone.net mail to provide free e-mails accounts to my members. Mail works fine I can sent and receive without any problem.

http://mail.certifyexpress.com

The problem is then I use vBulletin to sent e-mail for lost username and accounts it won't sent to any @certifyexpress.com e-mail holders. But it works fine with @hotmail.com and my other pop accounts.

What should I do to correct this?

Most likely the mail service is delivering the mail to you local machine since it is in the same domain.

If you are not using your machine for any local mail (mail being delivered to the box), you need to configure your sendmail not to consider your certifyexpress.com domain a local domain.

Let me know which operating system you are using and I'll point you in the right direction for reconfiguring your service.

I'm using RedHat 7.1 with plesk.

Hmmm. Not familiar with "plesk". Is that a mail program?

If you are using sendmail, make certain that /etc/sendmail.cw does not contain your hostname or domain name. Even if sendmail is not running in daemon mode, it refers to this file when sending outbound mail.

If plesk is a mail program, you will want to find out how to keep it from trying to delivery mail for the local domain to the local machine... unless you have a service structure that requires it. If that is the case, you'll need to set up a sub domain and have your email forwarded using a .forward file (or some other available mechanism).

Karyn, plesk is a control panel system: http://plesk.com

For plesk config files resides in /etc are useless. Here is what I've found out.

Ok, this is what is in rcpthosts and virtualdomains file. So I should delete certifyexpress.com domain? Just to double confirm. How do I restart qmail? I'm new to plesk so forgive me.

rcpthosts


certifyexpress.com
dns1.certifyexpress.com
dns2.certifyexpress.com
forum.certifyexpress.com
hardware.certifyexpress.com


virtualdomains


certifyexpress.com:certifyexpress-com
dns1.certifyexpress.com:dns1-certifyexpress-com
dns2.certifyexpress.com:dns2-certifyexpress-com
forum.certifyexpress.com:forum-certifyexpress-com

I'm not at all familiar with Plesk or any other control panel. But I use Qmail exclusively, so maybe I can help...

First of all, make sure your domain is NOT in /var/qmail/control/locals (or wherever Qmail's "locals" file is). Also make sure it's not listed in "virtualdomains" or "rcpthosts", though technically those should be ignored.

Second, make sure your local DNS reflects what the outside world sees -- this is most important. If your own box shows something different from what the rest of the world sees, local mail delivery will suffer.

Do an 'nslookup' on your domain first using your local DNS server, then using an outside name server (for example, an ISP name server). Make sure everything looks the same, specifically regarding the MX record.

If you're running a DNS cache as well, make sure it's not treating the domain as local -- make sure that requests for that domain are forwarded to outside DNS, not your internal name servers.

Just fixing Qmail will only cause the mail to bounce; the real problem is in DNS, since your mail is ending up at your own server, which is not where it needs to go (eg, it shouldn't even reach qmail in the first place).

Hope this helps.

The MX records for his domain have already been determined.

At this point, its the MTA config.
