SMTP settings to send email error

[henjoe]

Hi, I wonder who already use the SMTP settings of Fuxa?
I tried to use it but I am having failure, it says:
"https failure response for http://localhost:1881/api/sendmail:400 bad request"

Is my setting is wrong? (see below)

Hope someone can help me. Thanks!

Changing the port to 587 solves the problem.
