Have you tried a 'prefix' feature?Settings for Braintoss email delivery to (....@nirvanahq.in)
To change settings send a Braintoss note in the format:
set settingname value
For example "set footer off" or "set caps on"
Alternatively send a note with set plain to strip everything except the attachment or with set default to return to the default settings.
Use "set postfix ..." for adding a #tag or a @notebookname.
The setting change will apply to the email address that is being delivered to, this means you can have more than one set of settings as you can use multiple addresses in Braintoss.
