control: retitle 1070901 POP3 authentication failure and “error:0A00010B:SSL routines::wrong version number” (2 bugs)
After submitting this bug report, I picked up on the nuance “=> Send SSL data”, which differs from “=> Send header”. So whatever is happening with that SSL data may be unrelated to why authentication is denied. We still likely have a bug but it’s non-trivial to see what the issue is.
