I'm new to Apple Mail, having used Spark for years until this week.
I just used the Mail Drop feature for the first time and noticed that when I checked for the message in my Sent folder, it started to download the attachment; all 1.8GB of it!
I realise I can turn off attachment downloads, but I'd still like smaller attachments to be accessible.
One thing I've considered is using a folder trigger to delete attachments over a certain size from ~/Library/Containers/com.apple.mail/Data/Library/Mail Downloads
.
However, it would be preferable if attachments (e.g. >20MB) didn't download in the first place.
Has anyone else given this some thought?
