Programatically change subject line and forward mail - Google Apps

Question

Gmail groups email with the same subject line into a conversation view (threaded).

I've never had an issue with this functionality until I began using an online fax service (myfax). I can't label / store email from the fax service into different folders because it is all grouped up.

I am looking for a way to programatically break conversation view for incoming mail from a particular sender. I've gone through all the filter settings and looked at a lot of the Google Mail API. Is there a simple script I can run to pop and account by itself perhaps, add a time-stamp to the subject line and automatically forward it on? (MyFax gives me the option of changing the mailbox incoming fax notifications are sent to)

This shouldn't be too hard but I'm finding nothing in the way of doing this. Please help!

Note: MyFax does not allow any configuration of their outgoing emails (i cannot set it up on their end).

Answer 1

Gmail now has a feature to disable conversation view. Its under the General tab in settings. Unfortunately it disables conversations for the entire account. There's no way to selectively break conversations. The best you could do would be to use IMAP to access the problematic messages and rewrite them.

Answer 2

I found this answer in an Evernote Forum recommending the Tarpipe service:

Recently, I found a service called Tarpipe (tarpipe.com) that makes this process a lot easier. Tarpipe sets up a workflow that will process incoming e-mail and change the Subject line in any way that you choose and then forward it on to another e-mail address. So, for example, you have a newsletter that you get each week and you would like to save in Evernote. If you use Gmail, you go to the 'Create Filter' dialog and set up a filter that selects this email from your incoming e-mail.
