Send Emails issue

How the send emails feature works?

It is only working in a Intranet using company emails but when I tried to send an email to gmail for example it fails: "reason: 550 Host unknown."
However our outlook allows us to send external emails.

Have you tried the SMTP setting of gmail?

Gmail SMTP server address:
Gmail SMTP username: Your Gmail address (e.g.
Gmail SMTP password: Your Gmail password
Gmail SMTP port (TLS): 587
Gmail SMTP port (SSL): 465
Gmail SMTP TLS/SSL required: yes
