We are using the sender mail adapter to retrieve messages from an IMAP mail server. Messages are being picked up correctly, but when we have large messages (with e.g. PDF attachments) things go wrong.
The time it takes to retrieve the mail message is longer than the poll time. In this case the adapter logs in again in the mail server to retrieve the first new message from the inbox. However the first adapter threat is already retrieving that message. This results in a duplicate message in XI. (messages are set to be deleted when read).
We have tried all kind of settings in the adapter but without any results. The adapter works fine with very small messages.
Does anyone recognize this problem?
