I just installed eMail on an Ubuntu 20.04 machine, I have configured an SMTP server, but when I attempt to send an email I get:
$ echo "Test the eMail program" | email -V -s "Testing" redacted@mydomain.tld
Connecting to server mail.gandi.net on port 465
Init connection...
email: FATAL: Smtp error: Timeout(10) while trying to read from SMTP server
