Hi,
Joomla 2.5.7. / Documents Seller 2.7.0
This is for other's use. I was having a hard time configuring my mail settings in Joomla's Global Configuration>Server>Mail Settings. I use HostMonster for hosting. I called the HostMonster techs and they helped me to make the following changes which worked well.
Mailer - PHP Mail
Send Mail Path - /usr/sbin/sendmail
SMTP - Yes
SMTP Security - TLS
Port - 26 (unique to HostMonster)
SMTP Username - your email address
SMTP password - your password
SMTP host - localhost
In the .htaccess file these lines were added:
# Use PHP5.3 Single php.ini as default
AddHandler application/x-httpd-php5s .php
In the php.ini file, these lines were included:
; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = /usr/sbin/sendmail -t -i -f '(your email address)'
The php.ini file was in the root directory of the Joomla install.
Hope this helps someone. If anyone wants to give me tweaks, tips or other advice because this is not the most elegant solution, please let me know.
