have an old client who went and changed exchange hosts after around 5 years and the new host seems to be saying we can’t use smtp with their service. Just get straight up authentication errors.
They said we should use php mailer but I’m stumped. It’s super frustrating that they won’t allow us to use smtp as we did with the last crowd.
What are my options? I don’t really know how much work is going to be involved in getting a new solution up and running. They have a lot of forms as it’s a job site and I currently have a lot of auto responders setup via perch itself.
Sendgrid has been suggested to me.
