get rid of apache@localhost in received email headers

There is a good change that the foreign email servers will drop if the sender email headers are not properly formatted.
Anyway if you get apache@localhost in Received header (with postfix/apache/php), you can change the php.ini, sendmail_path program to use sendmail.postfix instead of sendmail binary.

like : sendmail_path = /usr/sbin/sendmail.postfix -t -i -f

working with “screen”

Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells). It is mainly useful to keep the sessions uninterrupted, especially when you run time consuming scripts.

$ screen
open a new session Ctrl+a+c
Scroll between sessions Ctrl+a+a

retain the sessions
$screen -dr

[Resolved] Postfix X-Authentication Warning

X-Authentication-Warning can appear on the mail header , when the user sending email is not trusted by the mail server. There is a chance that email are considered as spam because of this.

To fix it you can add the user to /etc/mail/trusted-users

If your system has forms that used to send email as apache user, you can add “apache” user to the trusted-users file.
