Question

I’m wondering whether it’s safe to mark bounce messages containing “This is a permanent error.” string from the first time?

When I get “This is a permanent error.” doesn’t mean “permanent error” for this message or for the user?

Answer 1

Depends on what the error code is. Check the message for a code, and compare it to one of these tables, which should tell you more.

Without the actual error output, I can’t give you a more specific answer.
