I'm using Postfix to forward emails from my Mac through smtp.gmail.com.
Following recent security update (https://support.apple.com/en-us/HT208221) Postfix fails to forward emails with the following errors:
smtp: warning: Digest algorithm "md5" not found smtp: warning: disabling TLS support smtp: TLS is required, but our TLS engine is unavailable
Here is a snippet from Postfix main.cf.
relayhost = [smtp.gmail.com]:587 smtp_generic_maps = hash:/etc/postfix/generic smtp_tls_security_level=encrypt smtp_sasl_auth_enable=yes smtp_sasl_password_maps=hash:/etc/postfix/sasl/passwd smtp_sasl_security_options = noanonymous smtp_sasl_mechanism_filter = plain
Any ideas how to get this working again?
