Mail Converter > Updating Tickets > Workflows do not run

Workflow(s) do not run if a ticket is updated via Mail Converter. For example, if I create a new workflow-:

Module = Tickets
Every time the record is saved
Condition = Comment is added
Tasks > Update field > Status = 'Open'

If a comment is added to a ticket record manually the workflow runs fine. If a comment is added by Mail Converter the workflow never runs. The consequence of this is that when Mail Converter adds a comment to an existing ticket there is no way to alert the vTiger users who manage the tickets. The only way to determine if a client has responded is to examine all non-closed tickets!
