Posting this for the benefit of search engines rather than the benefit of Erik, since I just ran into this making some changes to my own mail server... If you have a server enforcing TLS, Postfix as a client is normally good with this setting: smtp_use_tls = yes However, if you have transport maps configured (usually in /etc/postfix/transport), you may get errors like this in your logs: 530 5.7.0 Must issue a STARTTLS command first In this case, you need to set up a /etc/postfix/tls_per_site file to match your transport file, see "Mandatory TLS encryption" at http://www.postfix.org/TLS_README.html#client_tls_encrypt -Mary -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
