Re: Email Problems - please help

When I turned off send via SMTP and then tried sending the report I got the following.

An error occured while sending 'PDF Email Report - 1.2013-07-14.2.en.pdf' to quantumphotography@gmail.com. Error was 'Temporary local problem - please try later'

I am with " Justhost"

?? I presume they have mail server. The address I want it sent from is an actual email address I have setup in cpanel.
