Description

If an error occurs before routing an email (email corrupt), the consumer blocks and does not process further emails. A similar issue was fixed with CAMEL-7474, but the issue still exists at another location.

CAMEL-7474 introduced a parameter "skipFailedMessage", which is used in Line 291 of the MailConsumer. If an error occurs in "createExchanges" (Line 128) the parameter is not evaluated.

Example stacktrace:
