smtp connect failed

[hwp994108018]

Hello,
I have mailwizz installed, and have a remote smtp server ready, it works, and I have tested it via https://www.gmass.co/smtp-test.
However, when I add Delivery Server, the system displays an error “

• Connection could not be established with host IP :stream_socket_client(): Unable to connect to tcp://IP:25 (Connection timed out)
  Log data:
  ++ Starting Swift_SmtpTransport
  !! Connection could not be established with host IP :stream_socket_client(): Unable to connect to tcp://IP:25 (Connection timed out) (code: 0)

”

Most likely your hosting is blocking outgoing connections, this is why you could connect to the same smtp server from outside your host but not from within. Contact them and ask them about it.

This seems to have nothing to do with the outgoing block.

You need to test the connection to the smtp hostname using the port 25, so maybe something like

telnet my-smtp-ip 25

ping is really useless in this case, it does not tell you if you can or cannot connect on a certain host and port combo.
