Basic mail configuration for webserver and mailforwarding for root

Leave a comment

Till now I didn’t configured any mail support for wordpress but today I wanted to enable wordpress to send mails to me and became aware that I didn’t configure postfix for my system.

In fact a basic configuration is quite easy. If the webserver should be able to send mails to an address of your choice you may hav to adapt the follwoing parameters in the /etc/postfix/main.cf:

myhostname = vps.fawcs.info
mydomain = fawcs.info
myorigin = $mydomain

After those three parameters are configured the postfix service has to be restarted: systemctl restart postfix.service

If there are still no mails comming in check if the /etc/php.ini is configured to use sendmail_path = /usr/sbin/sendmail -t -i

I also recogized that there are some mail in the inbox for the root user so I decided to also enable mail fowarding to get new mails directly to my mail-address instead of the root’s inbox.

Herfore the last line in /etc/aliases has to be uncommented to look like:
# Person who should get root’s mail
root: yourmail@yourdomain.info

Afterwards the postfix service has to be restarted once again and in the future all mails will be forwareded to the system.

if you have troubles receiving mails the mailq command is helpful to debug problems with unsent mails or mails which get rejected by the receiving mail server. A look at the /var/log/maillog logfile is also worth a try. 😉

Display php-errors

Leave a comment

Mostly the following PHP.ini settings are enough to make php display errors in a production environement where error_reporting & display_errors are disabled in the PHP.ini.

[pastacode lang=”php” message=”” highlight=”” provider=”manual”]

ini_set('display_startup_errors', 'On');
ini_set('display_errors', 'On');
ini_set('html_errors ', 'On');
ini_set('log_errors  ', 'On');
ini_set('error_reporting', 'E_ALL & ~E_NOTICE');
error_reporting(E_ALL);

[/pastacode]

But in some cases there will not be an error message displayed. The only solution I found was to enable the dispaly_errors in the php.ini.
To avoid setting this aparameter globally it could also be set in the conf-file for the virtual host which worked for me pritty fine.

[pastacode lang=”apacheconf” message=”” highlight=”” provider=”manual”]
