Hi. Haven't been able to find too much info in terms of a layman's fix and my ISP is not much help. I have a business acquaintance that has been trying to email us business info from his work email as well as his AOL account. He keeps getting a bounce back with the message referring to SMTP 5545.7.1 (P4).
From what I can tell it has something to do with authentication when I google that error code. But don't know if it's on my end or his. Everything else works fine for both of us.
He doesn't get our emails and we can't receive his. I am using Thunderbird and my service is through Centurylink.
Thanks,
Jay
