Could not open socket towards the self server

  • Hi,

    I setup the plugin to send emails using the server itself, using the following settings:
    Type: SMTP
    Mailer Type: PostSMTP
    Outgoing Mail Server Hostname: I tried either localhost or 127.0.0.1 or the server’s public IP – all with the same result
    Outgoing Mail Server Port: a custom high numeric port where SMTPS of exim is listening, not the default/known port number

    In all cases of changing the target IP, as mentioned above – the result was “Could not open socket”

    So, I SSHed the server and telneted to this port using all the above 3 server definitions – and all resulted in TCP session “connected”.

    Is it possible that this plugin somehow does not allow accessing non-default ports?

    Thanks!

  • It might be that your web host or firewall on your server is blocking out-going access.
    Ask your webhost if they are blocking any outbound ports and have them add an exception for the port you need.

    I am the “host”, I fully control the server, end to end.
    As I wrote – I telneted locally to the relevant ports and all was connected, so no FW issue here.
