confirmation emails not going to yahoo address

[idoityourself]

Hi I just set up prestashop and Ive been doing some testing. I have a problem if a customer uses a yahoo account to register.

 

I get emails saying "Warning: could not send message for past 4 hours" and the email takes ages go through to the yahoo account, but does seem to eventually get there.

I've tested it with two different yahoo accounts and get the same thing.

Gmail works fine.

The contact form works right away, its just confirmations of registration and password requests.

 

Does anyone have any ideas?

thanks

 

 

Here is the full message I get

Just wondering if anyone has any ideas about this? Getting customers chasing up where their confirmation email is and they have yahoo accounts.
