need help with name displaying in front of my outgoing email

Hi,
my post earlier just disappeared. I have a name showing in front of my email address on out going mail that is not valid anymore. How can I fix this? even though on profile/setting everything is right.
"SADEH777< admin@econoprix.com>"
instead of SADEH777 its supposed to say "ECONOPRIX".
thanks for your help
