I want to set up sending notifications to sweat users, on a test machine I succeeded, but on a production server I can’t set it up
. : message-id=<[email protected]_Moscow.localdomain>

Jan 31 12:29:12 localhost sSMTP[8768]: SSL not working: unknown message digest algorithm (7)
Jan 31 12:29:12 localhost sSMTP[8768]: Cannot open smtp.gmail.com:587
Initially there was this error sSMTP[1332]: SSL not working: certificate verify failed (20)
then I added the line TLS_CA_File=/etc/pki/tls/certs/ca-bundle.crt the
errors changed... I can't find anything special about it on the Internet. ..Test message
mail -s test [email protected] < /dev/null comes to the mail, but if you leave a message, nothing happens.
nano /etc/postfix/main.cf

SSL not working: unknown message digest algorithm
This indicates that you may have an outdated version of openssl installed. Try updating it.
