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

[Olaf Skibbe via Alpine-info]

Hi Brad,

This reminds me strongly on an issue I found last year and discussed on 
the mailing list in February 2024 under the subject "Forwarded mail 
partially invisible in Outlook". Do you have access tho the old list 
mails? Otherwise I can forward them to you.

My result was that this is a bug in Outlook (both client and web 
interface), not an alpine issue. Outlook is obviously and reproducibly 
hiding parts of mails from its users.

My workaround is to forward messages with attachments as one mail 
attachment (by pressing "h" before forwarding with "f").
