i installed emclient

I installed Emclient a while back and all was well and GREAT, I love it.
2 days ago it stopped sending email.  It receives fine but no go on outbound.
I get this error.

Your from address (smokey@jsmokey.com, jsmokey <smokey@jsmokey.com>)
must match your authenticated email user (jsmokey) Treating this as a spoofed email

I even tried deleting the account and re-setting an account up

Hi Smokey,
can you copy the LOG from Tools>Operations>Log next time this error pops up?

Regards,
Olivia
