I need to set up Scan to Email on Konica Minolta but it keeps on failing to do so. 

Here is my setup!

Email TX setting is checked

Scan to Email is On

Email notification is On

Total Counter Notification is On

SMTP Server Address (Plese check to enter hostname is Checked)

smtp.zoho.com

Use SSL/TLS - I have 3 option here and I have picked (SMTP over SSL) - Other two are OFF and Start TLS

Port number - 587 (greyed out)

Port Number (SSL) - 465 

Can you please tell me what am I doing wrong here?
