Compose mail from the commandline ([Fedora](…/Fedora Linux/))

Installation (once)

This will install s-nail, a commandline “MUA” (Mail User Agent) with built-in SMTP (“MTA”) capability:

sudo dnf install mailx

The command mail will become a symlink to s-nail. Better verify this using:

ll -ld $(which mail)

Configuration (once)

set asksub  
set v15-compat  
set mta=smtps://apikey:SENDGRID_APIKEY_GOES_HERE@smtp.sendgrid.net:465 smtp-auth=login
set from=SENDER_ADDRESS_GOES_HERE

chmod 600 ~/.mailrc
