Hello, we have a problem with automatics replies by email.
When we make an update in a ticket, JIRA send automatics mail to informer and requests participants. We have seen that the email content the signatures and several errors of "unable to render embebbed object: File......", for this reason, the email that our clients receive looks very dirty.

Is there any configuration that can be done to prevent it from adding the signatures or at least getting them to appear correctly?
Thanks in advanced.
Regards.
