Good day all, i have an issue with sending email to a particular email address.

when i send email from my web page to this particular email address, it does not get delivered, but the CC and BCC gets delivered.

i also try using this email address as the CC it still does not get delivered.

but when i send from Yahoo to this emaill address, i delivers well.

what could be possibly wrong???

and pls note that there are no filter rules for this email address, also the web page am sending the email from is also on the same domain as the email address.
