Error code: status=bounced problem

Hello, I have some problem with my forum. Something wrong with emails.
Actually my forum is a rpg forum. So everyone have about 4-5 accounts and more. Some of them using random emails.
Sorry I can't explain this very well, I'm not native english speaker.
And the account vertify thing is weird. Actually yesterday everything was fine. We tried to change the emails, but didnt work.

The error thing is;

"The email address of your account no longer seems to be valid. This may prevent you from receiving notifications."

Error code : status=bounced (host mta*.am0.yahoodns.net[6*.195.22*.106] said: 554 delivery error: dd This user doesn't have a yahoo.com account (***@yahoo.com) [-9] - mta440*.mail.gq1.yahoo.com (in reply to end of DATA command)) ...

Is there settings for this? I searched the panel but couldn't find. I want to know why and because of this we are seeing the words with black color on the forum^^' this is so frustrating. I know we need to change emails again but I want to solve this problem. Why is this happening now? I need help

hello,

this is an error message sent back by your email host and that we display on your profile for information. it is intended to inform you that there is a potential problem with the validity of your email address. the details of the problem are given in the "error code" line.

it is a security that has been put on Forumotion forums to avoid blacklisting our mail servers.

in your case, the message is very clear, your email no longer exists and you should update it with another valid email.

thank you for your understanding

thanks
