Ok, I don't really think this is an issue with Swiftmailer, but I was hoping maybe I could get some advice.
I'm running a dedicated server, Domain name: bpmgpublishingsystem.com.
When I was using swiftmailer to send as localhost, i was having no problem sending emails.
When I changed it to send as bpmgpublishingsystem.com, All the emails I send don't go through
When I was sending mass emails as localhost I was getting a lot of error messages like "Remote host said: 550 Mailbox unavailable or access denied " So i'm thinking I'm getting blocked as spam, even though my server is not blacklisted and i'm not sending out spam.
