Hostname works on other SMTP tests, “Closed” in Postman and times out

    Trying to configure to send with a certain hostname. When I plug the same info into other services, such as Wormly or MX Toolbox, no red flags are raised and it looks like it should have no problem sending mail. Any test emails I’ve tried go through successfully.

    However, when I plug this hostname and port into the plugin and send a test email, it consistently times out. When I run a connectivity test, that port shows up as “Closed.”

    Is this a server issue? I can verify that PHP and WordPress configs are not blocking it in and of themselves. What are some other causes for a mailserver to be “Closed” when it isn’t actually closed?

  • Hi @hoylew,

    The is no logic test a host from external service because it can be open from there while your server settings are different.

    If you get a Connection Timed out error when sending email via SMTP , it means that you are using an SMTP port that is blocked by your host.

    Contact them to check the issue.

    Unfortunately, no; our webhost is also insisting that they are not the point of failure when the connection times out. We are as of right now still unable to figure out why port 25 is not working.

    Can you try another port ?
    465 or 587

    To my knowledge, the email provider for the mailserver we would like to use does not allow for service on those ports (this is confirmed by the “connectivity test” in the plugin settings).

    I don’t know what so important in this mail server but you can try other
    services like elastic email (150,000 free) or mailgun (10,000 free).
    No need to stuck with something that doesn’t work.

    Contact your web hosting.
    It look like some web hosts blocking external SMTP relay, for example godaddy:

    That was my thought as well, however our web host has claimed they are not blocking port 25. In fact, rather than “connection refused” as posted in the GoDaddy link above, we are simply getting “connection timed out.” I am not sure if that would make a difference.

    Despite inititally claiming otherwise, webhost support eventually admitted they block Port 25. Apologies for the delay in marking this closed.
