I'm trying to set up postfix to send mail through Gmail's SMTP server on port 587. Here's what I've put in my
relayhost = [smtp.gmail.com]:587 smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous smtp_sasl_mechanism_filter = plain smtp_tls_CAfile = /etc/postfix/cacert.pem smtp_use_tls = yes
However, I'm running into TLS problem since
/etc/postfix/cacert.pem, which seems to be suggested everywhere online, doesn't really exist on my system (OS X 10.9.3).
Therefore, what is the right CAfile to use? Any help is greatly appreciated.
On a side note, for now I'm using the workaround
smtp_tls_security_level = may
which works. However, I suppose this is a cheap fix, and I'm worried about the security.
