mail does not send big attachments with mail drop
Big Sur om Macbook Pro 2020
Mail does suddenly not send large attachments anymore, it asks for 'do you want to send via mail drop" then the mail goes to the 'drafts' folder and the attachmentis gone. (and mail did not send)
What I tried:
- a new user-account on same Mac, with same appleid, maildrop worked without problem.
- safeboot
- deleting cache-files from user library
- deleting com.apple.mail state from saved states
Does anybody have an idea to solve this?
Thanks
MacBook
