Hello, In an other thread I asked to see what postfix options are made empty/nil by adding in the file the option name followed by only " = " In fact there are more than I expected. Is it better to let the file as is, or to comment out these lines to get back postfix default? for example I notice "relayhost = " several options are listed in main.cf, I'm unsure to what is done if the option is not listed in the file practically, I didn't find a way (without breaking all the install) to list *default* options (that is what is done if the option is written nowhere :-() comm -23 <(postconf -n) <(postconf -d) (settings that *differ* from built-in defaults) gives relayhost = but, if I remove (rename) main.cf and stop postfix, # postconf -n | grep relayh postconf: fatal: open /etc/postfix/main.cf: No such file or directory that's ok, but: postconf man page: -d Print main.cf default parameter settings instead of actual settings # postconf -d | grep relayh address_verify_relayhost = $relayhost(...) relayhost = (...) so "relayhost =" should be the default, is the comm line wrong?? thanks jdd (confused) -- http://dodin.org http://valeriedodin.com
