Problem forwarding email on MacBook Pro, OS Catalina 10.15.5
I can forward many emails, but not all from my MacBook Pro running Catalina 10.15.5. I keep getting message that can't send message using server {then lists my gmail address]. One email is to my wife who uses a gmail account as well.
Recently upgraded from MacBook Pro 15" to new 16" but had to do manual install of programs, transfer from old machine to new machine did not work.
Can't figure out what to change to fix problem.
MacBook Pro 16″, macOS 10.15
