Regardless of settings in the softaculous control panel or if I use the PHP mailer or SMTP I can't get Softaculous to send email on completion of install or removal of software.
It does install the software and if I install Joomla, for example, Joomla can successfully send email.
I did see the following in /var/log/exim_mainlog when I set the emailer to SMTP :
2014-02-08 06:47:18 SMTP connection from [::1]:50187 (TCP/IP connection count = 1)
2014-02-08 06:47:18 SMTP connection from localhost [::1]:50187 lost
2014-02-08 06:47:53 SMTP connection from [::1]:58776 (TCP/IP connection count = 1)
