Was that a typo? It should have been a slight superset of the previous
log lines.

(you had all the ones from your IP
-> which showed that process number 7953 handled the connection in question
-> so getting all of PID 7953's logs at once is handy)

Next question is: why is SASL auth failing?

* Is it working for other people?
* Are there helpful debug settings?
* [MDD] asks: Does postfix use saslauthd like sendmail does?

I assume it's easy for you to reproduce the problem with Mailspring?
Can you reproduce it with swaks in a way that someone else can try?

Nick.
