Problems with email setup & access admin email & can't recive email

[BulleT]

I've change it in admin/settings_welcome_mail.php


IMAP/POP3 is on

Code:

Hi. This is the qmail-send program at yahoo.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<adrian@nitescu.info>:
86.126.159.38 does not like recipient.
Remote host said: 451 4.3.5 Server configuration problem
Giving up on 86.126.159.38.
I'm not going to try again; this message has been in the queue too long.

Maybe when I changed the IP, IMAP/POP3 is listening on the old IP that is not in use anymore?
