Setup Postfix following flurdy tutorial

[dan...@gmail.com]

Hi friends,
For the first time, I'm trying to configure postfix on my vps (Ubuntu Xenial), using flurdy tutorial: http://flurdy.com/docs/postfix.

Now I've setup partially the entire mail system, and I can to connect to the email server with telnet from localhost, but obtain two warnings:


postfix/pickup[5045]: warning: /etc/postfix/main.cf, line 81: overriding earlier entry: alias_maps=hash:/etc/aliases
postfix/pickup[5045]: warning: /etc/postfix/main.cf, line 82: overriding earlier entry: alias_database=hash:/etc/aliases



This is my postconf -n:

what it depends on this warnings?


Many many Thanks! :-)

WAG, check your actual main.cf and see if you have the entries repeated
somewhere? My setup also on 16.04 with no warning...

~$ grep alias_ /etc/postfix/main.cf
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf

Take care,

Duplicate main.cf entries (in this file or in included files in /etc/postfix)
