I am having major problems with mail configuration. Forgot about mail when switched my drupal site to unmanaged VPS which has already taken me two weeks to work out how to install via command line.
Realize now drupal cannot run for signups or any mail related jobs without first setting up mail on the VPS.
So followed this tutorial : http://www.techotopia.com/index.php/Configuring_a_CentOS_Postfix_Email_Server#Starting_Postfix_on_a_CentOS_System
Does it work for me? nope. I get the following errors:
-bash-4.1# postfix start
/usr/libexec/postfix/postfix-script: line 317: cmp: command not found
postfix/postfix-script: warning: /usr/lib/sendmail and /usr/sbin/sendmail differ
postfix/postfix-script: warning: Replace one by a symbolic link to the other
postfix/postfix-script: starting the Postfix mail system
Since reading that tutorial I have read many others and ended up making all of the following edits in my postfix main.cf file but I really have no idea what I am doing esp with my drupal site installed in a subdomain folder!
And haven’t even got to the database side of things yet:
myhostname = myservername.sub.mysite.net
mydomain = sub.mysite.net
myorigin = $myhostname
myorigin = $mydomain
inet_interfaces = all
inet_interfaces = $myhostname
inet_interfaces = localhost
mydestination = $myhostname, localhost.$mydomain, localhost
mynetworks = 192.168.0.0/16, 127.0.0.0/8
Hope someone will steer me in right direction. Feeling overwhelmed by it.
