+mms_us_metropcs
+---------------
+This is a prototype module to try and clean up messages that are posted via
+the MMS feature of a mobile phone. The emails generated this way typically
+contain additional logos from the service provider, and possible additional
+text.
+
+hook_mailsave_clean is triggered by mailsave before it calls hook_mailsave.
+You can therefore intercept the node and the email attachments before
+other modules begin processing.
+
+By implementing hook_mailsave_clean in a module you can therefore discard
+additional images that are attached and modify the text of the node.
+
+hook_mailsave_clean passes the node, but also information about the mailbox
+and the email that is currently in use.
+
+--------
+
+MetroPCS messages are identified by being from @mymetropcs.com. The 
+messages are plain text, but have a long string attached to the end 
+which is stripped. There are no additional attachments to remove.
