Question local mail problem

[cempehlivan]

Hello,

For example, I have 2 domains on Plesk and I use the mail service (mailenable) on both. abc.com and def.com. Then I redirected abc.com mail settings to yandex. Both my mails work fine, but I cannot send e-mails from def.com to abc.com. It sends to the old mailbox on the server. The mail I sent from def.com to abc.com is sending to the local box. How will I solve this problem?
