We set up the incoming email according to documentation and besides the wrong documentated keyword "Assignee", everything seems to work correctly.
We can see that incoming emails are truncated whenever one of the lines defined in "Truncate emails after one of these lines" is found - the rest of the mail is simply dismissed.
What we do not understand is what the entry configuration in "Truncate emails matching this regex" is good for. It implies that we may put in a more general expression than simply putting a string in the config above, but be more flexible. What will happen using this is that the matching string for a given regexp is simply removed from the email. The Email itself is not truncated in a sense that after matching regexp the mail is dismissed.
Is this what it is meant to be used for? What is the business case to cover with this feature?
Any help or hint is appreciated.
