i am currently having problems with my mail software. all mails i send out to yahoo addresses are not received by the receipient. all mails i send out to non-yahoo addresses get received. i tried using my webmail to isolate the problem. all mails i send out from webmail gets received by its respective receipient whether yahoo or non-yahoo address. with this, i believe that the problem is not with my host but rather my application. this is weird because before this happened, i didn't even adjust any settings at all. plus, this just came all of a sudden. any suggestions or remedy to this problem? advance thanks!
It happened to me before...what I did was to re-create my Gmail account in my Mail App and everything went back to normal. Hope that will work for you as well.
