Subject [jira] [Commented] (CONNECTORS-1260) Loop in emails processing
Date Thu, 26 Nov 2015 14:32:11 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1260?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15028895#comment-15028895

Karl Wright commented on CONNECTORS-1260:
-----------------------------------------

Hi Julien,

One of these problems is straightforward to fix; it looks like the emails you are fetching
are simple text/plain, and that was not handled properly by the connector.  I've attached
a patch for that.

The other problem is a bit of a mystery, since it wouldn't have anything to do with the email
connector at all, and would represent a general kind of problem we should see in lots of other
connectors.  Still looking at that one to see what it could possibly mean.
