Hi again,
Thank you for answer. My DNS conf. is here;
Host Record type Value
yakacikvalf.com.tr. NS ns.yakacikvalf.com.tr.
mail.yakacikvalf.com.tr. A 217.195.205.114

ftp.yakacikvalf.com.tr. CNAME yakacikvalf.com.tr.
www.yakacikvalf.com.tr. CNAME yakacikvalf.com.tr.
yakacikvalf.com.tr. MX (10) webmail.yakacivalf.com.tr.
217.195.205.114 / 24 PTR yakacikvalf.com.tr.
I can see my mail server's web mail service with webmail.yakacikvalf.com.tr address. It's OK. But mails are failed. This is a error;

553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
