Hello,

yes, if it is not working and also deprecated, if probably should be removed. You could open an issue for that or create (even better) a pull request.

Cheers,

Henning

Hi Daniel,

Just an update, I tested this with username_format set to 1 and set the
To: and From: headers to be the phone's username (ie without the timestamp). This worked without problems.

However, setting the username_format to 0 (the deprecated option) does not work even with the correct To: and From: headers. Since this option is already deprecated perhaps it could be removed in future versions to avoid confusion?
