Can we telnet to the smtp.hubapi.com to test our SMTP API credentials?

[DaxAT]

Before we update our server's SMTP configuration, we wanted to make sure that the credentials we obtained by creating an SMTP API token works.

Is telnet into the SMTP server permitted?

If telnet is not permitted, how can we confirm that our SMTP credentials are valid?

Hi @DaxAT,

I hope all is well with you 😃

While I'm not too familar with Telnet, digging into it, it seems that you may want to avoid using Telnet as it suffers from serious security issues. 

That being said, I'd suggest for you to check your credentials validitity in your HubSpot portal (Marketing > Email > SMTP tab) where it'll display your all your SMTP tokens information and from there you can also click to generate smtp token. You can learn more here: SMTP API Overview | SMTP API

Hope this helps to clarify!

Thank you, Wendy.

We went through the SMTP API token creation process.

We're not very familiar with modifying our SMTP client to connect to an SMTP service that requires authentication. We wanted to confirm our credentials before we tried switching over.

I'll create a post asking whether the UNIX sendmail can be configured to work with HubSpot and if so, how to set it up.

Thanks again.
