Support » Plugin: Postman SMTP Mailer/Email Log » Oh, bother! … Connection refused

  • Resolved gld


    Can’t seem to get OAuth working. Have followed the instructions at:

    Couple of things:
    – my Gmail account is using my own domain name (although I’ve ensured that the same email address is used throughout)
    – my web site is using SSL (https) so not sure if that is causing the issue.

    I’ve tried resetting the secret, the consent is done etc. but nothing seems to work. When I use Postman to send a test email, I always get the ‘Oh, bother! … Connection refused’ message.

    Connection refused means that Postman could not reach your mail server.

    Either (1) you entered the wrong port for the mail server or (2) your host has placed a firewall between your WordPress site and the mail server.

    Use the Port Test to determine which ports are available to you.

    Thanks Jason. The test came up as follows:

    Port 25 Open
    Port 465 Failed – Connection refused
    Port 587 Failed – Connection refused

    I know I need port 465. I’m hosted on GoDaddy and wouldn’t think they would be blocking this port??

    I ran the tests form my dev site and had no issue at all. Seems to be a problem with GoDaddy which others have also run into. Calling them now to try and resolve. Thanks.

    Yes, GoDaddy blocks access to external SMTP. You’ll have to make do with the GoDaddy mail server or switch to another host. You could ask them to unblock the ports but I doubt they will.

    Thanks Jason. Yes after 2 hours on the phone with them today being mislead down the MX record path, I finally got someone who admitted that it was blocked and won’t be changed. I’ve so had it with GoDaddy. The whole reason to go outside their email is because their email doesn’t work properly with too many of the emails being intercepted by spam filters because of their lack of efforts to set it up properly e.g. the lack of DNS reverse record etc. It’s a hot mess. Anyway, I’m done with them.

    Do you have recommendation on a hosting provider who doesn’t force me to listen to hours of the same music on hold each month?

    I just switched to OpenShift, myself. You get up to three WordPress sites for free. Aside from having to restart the app every time I update a plugin, their platform has been pretty amazing.

    Thanks Jason. I’m checking it out presently. Remarkably they aren’t blocking any of the ports!!

    Hi gld-

    I have a new version of the plugin that can send Gmail on port 443, that’s the HTTPS port. It is very likely that this port is open on your host. Would you like to try the new code?

    Thanks Jason! I plan to however I need to get my web sites off of GoDaddy since their policy firmly locks port 443 closed. I tried Openshift however because they don’t provide a fixed IP address, I cannot lock a naked domain (A Record) to it. The best I can do is use a CName of ‘www’ to put to it. Not good.

    I’m now trialling Amazing Web Services which are astonishing good and provide total versatility to manage everything including cloud performance right down to port control. Further I get an IP Address for each ‘instance’. I’m just stuck on trying to get SSL working but once that’s done, I can then get back to using your plugin. Thanks Jason!

    Whoops, I think you misunderstood the details in my post. Granted, I don’t use GoDaddy, but I do have an account there ( for testing and as far as I can tell, port 443 is open.

    See this screenshot.

    I’ll be interested to know how Amazon works out for you.. please let me know.

    You should check out Digital Ocean. All ports are open by default and their support is amazing.

    ALL GoDaddy shared, VPS and dedicated hosting have Ports 465 & 587 blocked. Port 25 is redirected through their proxy server to use their internal relay hosting.

    Here is a tip for flawless email delivery with a GoDaddy hosted website.

    @awtx, if you read the thread, you will see the Postman Gmail Extension was specifically created to send Gmail out on GoDaddy, without changes to GoDaddy config. In fact it will work for any host that blocks the standard secure mail ports (465/587).
