E-mail Server does not connect to the expected Configuration Server port in the following scenario:
- Configuration Server has an 'autodetect' port configured in addition to a 'default' port.
- At startup E-mail Server connects to the 'autodetect' port.
- The primary Configuration Server is stopped.
- E-mail Server reconnects to the 'default' port of Configuration Server backup instead of the 'autodetect' port.
As a workaround, in the E-mail Server Application configure a connection to the Configuration Server Application, selecting the 'autodetect' port.

Under high loads on the database, to avoid inconsistencies such as duplicated inbound e-mails, E-mail Server should have the timeout of its connection to UCS set to a higher value than the sum of the two following values:
-The timeout of UCS's connection to its Database Access Point (DAP). Default value is 60s.
-The value of the UCS option third-party-max-queueing-time (in the 'settings' section). Default value is 15,000 ms.
This means that the E-mail Server option settings/ucs-reconnect-timeout should be higher than 75,000 ms; for example, 80,000 ms.
