We are using java mail 1.4.4. I think this is pretty new although ~ 1 month ago java mail 1.5 was released.
Short update from our testing/analyzing: It seems the problem occures when mails are arriving on the mailbox while MailConsumer is working. I have created a test scenario where I loaded ~320 mails into the mailbox. The subject of the mails where the numbers 1-320. Then i created a route where I just take the mails from the mailbox and move them to a file-endpoint. As filename I took the subject, so it's easy to see which mails are missing. In this scenario I started the route after all mails where sent to the mailbox. Looking at the file-endpoint, there were all numbers from 1-320. My second test scenario is extended with an extra route. A route which just sends 10 messages every 5 seconds to this mailbox. The subject is still numbered. Looking now at the file-endpoint there were some numbers missing every now and then, but all mails in the mailbox were marked as seen. So I can reproduce the problem of our customer. I will try to update to a new Camel version and run this scenario again, maybe you can get me a hint how to get all the referenced libs that have changed since 2.6.0. We don't use maven so it is really hard to upgrade the referenced libaries for all camel components. kind regards, Christoph Claus Ibsen-2 wrote > You can also try upgrading the java mail JAR -- View this message in context: http://camel.465427.n5.nabble.com/MailComponent-MailConsumer-misses-Mails-tp5733010p5733109.html Sent from the Camel - Users mailing list archive at Nabble.com.
