Mail() function doesn't work

Hello Guys! I’m having a problem to configure the mail() function. I followed this tutorial, but still i’m getting some errors.

When I try to send an e-mail the SSH freeze for a few minutes and after display: “ssmtp: Cannot open”.

I already configured the firewall to allow data through that port, but still I can’t connect.

sudo nano /var/log/mail.log Feb 20 21:07:14 Estudar-Engenharia sSMTP[5013]: Unable to connect to “” port 587. Feb 20 21:07:14 Estudar-Engenharia sSMTP[5013]: Cannot open


Double check that the port number is correct. Maybe try 465 as mentioned here?

Hi there!

You may want to open a ticket and make sure that SMTP is not blocked on your account. Under certain circumstances SMTP may be blocked on signup and we would just ask you a few questions to enable it.
