Version 0.9 of vvmd is out!
https://gitlab.com/kop316/vvmd/-/tags/0.9
This fixes the issue with some T-mobile servers, but requires this patch with curl (which I am hoping will be merged soon). The patch is here:
https://github.com/curl/curl/pull/8986
It also fixes an issue I ran into where curl seems to sometimes say things went bad when they did not, and when this happened with the delete command, it ended up deleting the VVM on both the phone and server....which is not fun. This is fixed now.
