LF Help with LUA-TSM/Postal addon (Bugs out)

I've got both Postal and TSM Mailing. Postal used to auto-refresh the mailbox after the wait and it does not anymore with the version I got off of the wow legacy site. In addition, TSM works fine until you get mails that contain items in them other than gold. When these mails show up in your inbox, it bugs and shows nothing unless it bugs and happens to show the first mail item in the background that you can shift-click your way through until 'item mails' are all collected and then it starts working properly again. I can use either addon... I just need one of them to work.

Does anybody know LUA that can help me get one or both of these addons working properly? If so, I can host the file somewhere for others to be able to download the fixed version as well.

Here are links to the two I currently am using:

Any help is greatly appreciated.
