Quick fix for really slow PHP mail()

Saturday, November 1st, 2014

To fix painfully slow PHP mail function (you are also probably getting lots of

unable to qualify my own domain name

errors in /var/log/mail.log), make sure that both localhost and localhost.localdomain are in your /etc/hosts file: localhost localhost.localdomain

Also add localhost.localdomain as new line to /etc/mail/local-host-names file.

As the last step, restart sendmail:

service sendmail restart

You can quickly test by running:

mail -s "Test Email" your@email < /dev/null
