[jira] [Created] (JAMES-2682) Infinite loop can be triggered upon
Sieve failure
Tellier Benoit created JAMES-2682:
-------------------------------------
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 https://gitter.im/apache/james-project
