Hello M Haseeb

We are using a Zimbra mail account and I have included a link to settings screenshot here: https://voipchester.com/post.png

Many thanks for taking the time to reply, I hope all is going well.

Thank you

@lemondropcreative Goto Post SMTP Settings > Message tab and add the email and name, then test it and let me know.

Thanks

Hello

Many thanks for the reply, sorry I had not added that.

The postman now says it is configured but I get the error below when sending a test message:

Connection timed out

Thanks again for your help.

@lemondropcreative Please share Post SMTP connectivity test report.

Thanks

Hello

I have linked to the report here:

Many thanks

@lemondropcreative

You need to talk to your Hosting support about this; Your Email Ports are unavailable, so share the report with the Hosting support and then let me know the support response.

Thanks

Thank you for your reply and advice.

I will contact the hosting support.

Hello, thanks again for your help.

I contacted the mail server provider and they said:

Port 587 is available on the Zimbra platform, all email account are working as expected.

Not sure if that helps really as the connectivity test says it is open but not available.

Thanks again.

@lemondropcreative

Goto Post SMTP Tester here, fill in the required details and your email account details, and then test it and let me know the results.

Settings:

Select Host: Custom SMTP

Add your Outgoing Server, Your email Port, and select TLS.

and then fill all other details , test it and let me know.

Thanks

Hello

Hope all is well there.

That works, the email is delivered with the message: This is just text for testing.

I have tried again from the wordpress site with the same settings and get the message:

Could not open socket Your hosting is blocking the connection, contact their support

Many thanks for your help.

Hi @lemondropcreative ,

Thanks for getting back. It seems clear that your SMTP settings are good, but the service is being blocked on the hosting level for some reason which you may have to request them to resolve it for you.

The other option for you is to try some other SMTP service like Sendinblue, which may be an easy way get things resolved on your end.

Still do let us know if there is any question or confusion we can help you with.

Thanks and regards,
Support Team – WPExperts
