Hello, we have had some real nightmares this morning. We have been using email2case to automatically generate tickets. This morning we have been seeing some problems with duplicate tickets being generated. The emails all seem to be fine. We have looked through the logs and found they all seem to have the following message.

2005-09-21 09:02:21,273 424441124 [Timer-0] ERROR com.sforce.mail.GenericClient  - javax.mail.MessagingException: A9 NO Some messages in the mailbox had previously been expunged and could not be returned.;
  nested exception is:

The email got processed twice and so a duplicate ticket was issued to the customer

Does anyone have any experience of this and could anyone help me on this issue. It is proving to a real pain in the a*&!  ;¬)

Many thanks for your help
