Can't send emails for MacPro
I had same issue with iPad telling me user name or p/w is incorrect, but as soon as I posted problem to community it cleared itself, probably coincidence, but I never changed anything in settings and it cleared. Now I can't send from MacPro. I can send via webmail for aol so not the end of the world but it's a nuisance and I prefer my Mac mail. Anyone else experiencing this? I at first attributed these problems to pandemic going on and everyone working from home and high demand on internet, but not sure!
Thanks.
MacBook Pro 13", macOS 10.13
