Describe the problem/error/question

Hi everyone,

Since this weekend, every SMTP node I set (even with different emails and servers) have the same problem : connection timed out.
Does anyone has the same issue ?

Thank you :slight_smile:

What is the error message (if any)?

The connection timed out, consider setting the ‘Retry on Fail’ option in the node settings

Please share your workflow

Share the output returned by the last node

Probably because of this.

That is very bad news…
Do you have a workaround ? (except SendGrid)

I suspect you’ll run into similar limitations with a lot of hosting services. It’s too bad smtp was designed at a time when there was a lot more trust on internet services. Apparently there are not too many options for fixing it now, so services like sendgrid are necessary to add guardrails outside of the core mail-forwarding function and prevent “bad behavior” from triggering defenses (IP bans, etc.) in other places.

I think there are some hosting services that might agree to unblock smtp ports once you have provided some assurances. Not sure which ones though. I guess just start searching. Good luck!!

I’ll try using Microsoft Outlook API as my client has a Microsoft 365 account. I hope it will work.

I guess using Gmail node will also work for Google Workspace accounts ?
