-------------------------------------
Summary: Infinite loop can be triggered upon Sieve failure
Key: JAMES-2682
URL: https://issues.apache.org/jira/browse/JAMES-2682
Project: James Server
Issue Type: Bug
Components: Mailet Contributions
Affects Versions: master, 3.3.0
Reporter: Tellier Benoit
As pointed out by [~pleira], failing sieve processing can generate an mail
infinite loop.
SieveExecutor::handleFailure sends a mail to the user, that is also SIEVE
processed (and thus fails) creating a loop.
To prevent this loop, we should avoid Sieve processing on Sieve error
notification emails.
In Sieve executor, position a `"SieveNotification" -> true` mail attribute in
`SieveExecutor::handleFailure`. In SieveExecutor::execute check this mail
attribute and if present and true, do not perform the execution. You will write
a unit test in SieveIntegrationTest - Emails with this attribute should not be
processed.
If you have any issue don't hesitate to reach us in
