I've setup my email accounts to Zoho and they're working fine on ThunderBird (I can send/receive emails without any problems).
In order to make Contact Form 7 I've to configure the SMTP settings for the plugin WP-Mail-SMTP but I'm not having any luck.
I've tried the following tutorials:
https://www.digitalocean.com/community/articles/how-to-install-and-setup-postfix-on-ubuntu-12-04 -> it just doesn't works, I followed the guide to a T but it doesn't sends emails.
https://www.digitalocean.com/community/articles/how-to-use-gmail-or-yahoo-with-php-mail-function -> but I can't find /etc/msmtprc and ~/.msmtprc on my server.
I'm not very good at all this stuff and I'm trying to learn as fast as I can but in this case I just can't make it work :(
Any help will be greatly appreciated.
