Based on these log snippets, it appears that 

  on laptop A ...

  - you are using an id/pw, not OAuth2, for pop (port 995) email
    retrieval.
  - for sending you are using OAuth2, but are are trying to
    connect to port 25, rather than 465. that will fail.

  on laptop B
   - there was no retrieval attempt,
   - you tried, but failed, to get an OAuth2 token for sending 
     (on port 465).
      - it seems to fall back to id/pw, which failed, when OAuth2
        fails.
