VPOP3 received the error "554 (m1pismtp01-025.prod.mesa1.secureserver.net) (failed)"
This is the return message I constantly receive when emailing a particular supplier from the Mail App. It doesn't happen when I send from my PC, but every time I send from my MacBook Pro, this is what I get. Any ideas? I've tried sending in Rich Text and Plain Text format. I also have a signature that is an image rather than an actual signature because Mail won't allow me to insert a logo to my signature. Would this be a cause for corruption in the email?
