20210319- quick books mail send broken after 2017 to 2021 version upgrade.

Description of failure:

• 2017 version sent forms without issue.  No changes made to settings, computer, or network.  after 2021 upgrade, forms do not send.
• mail server not the issue as mail client on same system connects to same mail account without errors.
• all credentials triple checked, attempts to send with and without ssl on ports 465 (functioning for thunderbird) and 587.  Without encryption on port 25.  Error logs on mail server for these connections shown below

Steps taken to attempt remedy:

• update quickbooks
• QBW.ini edited to include:
  [QBWEBMAIL]CUSTOM_CERT_ENABLE=1
• quickbooks completely uninstalled, old instances of quicbooks2021 folders removed, program reinstalled/updated QBW.ini edited to include the above line
• same result when using the “other” mail server option or the “outlook” mail server option (but changing server credentials to match our mail server)
