Emails suddenly stopped sending / server time out and port 465 closed error

Hi Lauren,

That’s really unusual – the connectivity test failure is usually caused due to a firewall problem on the server. It looks like you are using a VPS from TSOHost?

Are you able to send mail from other SMTP accounts on the same server, for example through Thunderbird?

Kind Regards,
Tim

Hi Tim

Yes I’m able to log into the server and send emails using roundcube and horde for example and emails externally are working fine – seems to be just the automatic WordPress emails that have stopped.

One error is this:

You getting this message because an error detected while delivered your email.
For the domain: https://www.cherryred.co.uk
The log to paste when you open a support issue:
This email has empty body

And the other is this:

You getting this message because an error detected while delivered your email.
For the domain: https://www.cherryred.co.uk
The log to paste when you open a support issue:
cherryredrecords.servers.prgn.misp.co.uk has timed out

The hosts say there is no issue so I am a bit at a loss as to what has happened as it was working fine up until a couple of days ago.

The only other thing I can think of is I updated woocommerce to the latest version – is there a glitch with that do you think?

Cheers
Lauren

Hi Lauren,

Thanks for the additional information. I’ve got a customer running the latest WooCommerce and Post SMTP also at TSOHost, albeit on their shared platform rather than VPS. Unfortunately they haven’t got any orders that I can test with or see to confirm whether or not that’s the issue. I wouldn’t expect that to be the issue to be honest.

Can you paste a copy of your Post SMTP diagnostics log please?

You could also try swapping the hostname for localhost. As you’re on a VPS, with your web and SMTP on the same server that should work for you.

Would certainly be interested to see the results of a connectivity test to localhost actually?

Kind Regards,
Tim

I am also getting loads of email notifications coming through with this error:

How do I at least stop the emails as they are clogging up my inbox?

Cheers!

Hi @laurena86,

Apologies for the delayed response.

Did you attempt to set your mail sending hostname as localhost? As you are on a VPS with web and SMTP services on the same physical server this should work fine in your instance. Please test this and let me know the outcome of your testing.

To disable admin notification emails, head into ‘Show All Settings’ in Post SMTP settings and then into the ‘Notifications’ tab. Where you’ve got the ‘Notification Service’ drop down, change this from ‘WP Admin Email’ to ‘None’, and that should stop those notifications. Note that this will no longer alert you about any Post SMTP failures by email.

Hope this helps.

Kind Regards,
Tim

Hi @laurena86,

We haven’t heard from you in a while, so I’ll mark this thread as resolved. If you have any further questions please feel free to open a new thread, and link to this one.
