Vtiger - How to do settings for outgoing server when you don't now about SMTP server details

By doing some minor tweaks in core file we can easily enable default sendmail instead of SMTP settings.

In CRM, open file vtigercrm/modules/Emails/class.phpmailer.php

Changes should be as below:

function IsSMTP() {
$this->Mailer = "smtp"

to

function IsSMTP() {
$this->Mailer = "sendmail"

Now go to outgoing server settings in CRM admin and enter details like below -

Server Name:	mail.yourdomain.com
User Name:	youremail@anydomain.com
Password:	Your password for above email
From Email:	Set as per your choice
Require Authentication:	Set as per your choice
