Qmail installation on

Looking for Linux Server Admin or WordPress Expert? We can help.

Last two days i was working on to replace sendmail with Qmail.

I have completed installation with Qmail, Qmailadmin, vpopmail and vqadmin.

Now all websites on is sending mails with Qmail. This Free Hosting servers have no email account, only use of qmail is to send emails through PHP and perl scripts.

For testing, i change MX record of the domain name to so all mails are now processed by qmail. Receiving part is ok, i can receive emails with my favorite pop3 client outlook express.

But getting following error while sending mails

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was ‘[email protected]’. Subject ‘Testing from s12’, Account: ‘’, Server: ‘’, Protocol: SMTP, Server Response: ‘553 sorry, that domain isn’t in my list of allowed rcpthosts (#5.7.1)’, Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCC79

Think some thing wrong with qmail relay settings, have to figure out….
