[Alpine-info] Alpine-generated message in forwarded mail not seen in Outlook

[Brad Chamberlain via Alpine-info]

Hi Olaf —

Thanks for the pointer to that thread and your summary of it.  I can 
indeed read the archives at

 	https://mailman23.u.washington.edu/pipermail/alpine-info/2024-February/thread.html

and probably even saw the thread when it was originally posted, but 
obviously did not mentally retain it.

Thanks again,
-Brad
