SMTP settings with Zoho mail

Hey guys,
Do you have experience with Zoho mail? Using Gmail as smtp works fine, but Zoho doesn't.
I have a Ubuntu server, no cPanel. I've created a info@mydomain.com email address on Zoho, all DNS records set and it's working with desktop and mobile email application.
These are my settings in Opencart 2.0.1.1
Mail protocol: SMTP
Host: ssl://smtp.zoho.com
username: info@mydomain.com
password: ********** It's doublechecked and correct. It contains % and & characters too.
port: 465
The same email address is set on the General tab as E-mail.

I've also tried to change the mail.php based on this patch: https://github.com/opencart/opencart/issues/3756
$this->from to $this->smtp_username

Contact page is working, info@mydomain.com gets the messages.
When I try to send like a password reminder to a user email, I've get this error message:
Notice: Error: Password not accepted from server! in /var/www/mydomain.com/system/library/mail.php on line 288

I've read somewhere that when I want to send email from a server on mydomain.com using an smtp email like info@mydomain.com, that could be a problem, but I didn't find any working solution.

Thanks for any help.

It's been resolved. Password should not contain special characters.
