I am working as Insurance broker. I used to send emails to clients with insurance quote from Safeconow.com website. Since last week and a half, every email I sent from this website is undelivered and I get notice in my Yahoo account.

I checked with Safeco and if they send email to me and client from the same website, I get the same reply.

My computer help guy also could not help me!!

Can any one help me?

No, could they have identified you perhaps, thinking you are sending spam out? Also, do you have a virus in computer ?

But you are not using a company email to send out quotes ? Why?
