Intermittent conenction errors

Resolved pb52

For about a month now we’ve had an issue on several servers that POST SMTP is unable to send email because authentications fails or, most often, connection times out.

It happened again last night. At 23:18 we got a connection failure and that continued through the night – several service email were due to be sent but did not go. At 07:18 this morning I sent a test message, which worked. So the service healed itself.

Logically the issue would appear to be with the receiving mail server, but ours is the only service having problems, of many running on that server. But all the others use Easy SMTP. I like POST SMTP because of it’s email log, which allows me to resend failed emails and that feature is a godsend given our situation

Can you offer any advice please?

We’re using 2.3.2 free version

Hi @paulbarrett1952

I hope you are doing well.

Please share Post SMTP diagnostic test report, so then I can check and get back to you with a solution.

Hi, in attempt to break the deadlock I tried configuring one of our dev servers to use the Gmail API, since our main email service is hosted with them, instead of the mail in a box service provided by our website host.

We already have a service to backup Gmail to our Synology NAS using Synology’s Active Backup for Gmail, so I added an additional service for Post SMTP. We have two dev servers and two live, so I added 4 Authorised JavaScript origins and 4 Authorised Redirect URIs, corresponding tot the four server URLs

I added the client ID and secret on one of the dev sites. It was accepted and I authenticated the email address as suggested. That was a little weird, because Gmail did not ask me to allow the Post SMTP service. Instead it asked me to allow the Gmail Active backup. However, it seemed to work because a test message was sent and received with no authentication warning message.

So then I tried to set up the second dev server using the same process and credentials. That worked, up to the point of Gmail authentication. The normal Gmail box opened up, asking me to allow access (again to the Gmail Active Backup, not Post SMTP) but this time Gmail responded with “You are not authorised to use this service.” So I can send test emails but on receipt they all contain a warning that the sender could be authenticated.

Do I need to use a separate email address for each server?

No you don’t need to use a separate email address for each server.

Share the screenshot of email which you are facing warning.

Thanks

Did you enabled the Gmail API in your Google Cloud console ?

Its seems like Google cloud console settings are not done correctly.

Watch this video and configure the API again with Post SMTP and let me know.

I’ve been through the process again, with the same result. I can configure the first server, connect it and send a test message, but when I try to use the same creds to connect to a second server, I can complete all the set up steps but as soon as I try to allow Gmail to be used, I get the error that I’m not authorised to use the service. All of the authorised JS origins and redirect URI’s are defined – four pairs of them
