Added more details on SMTP authentication

Team, I was trying to improvise the documentation while I try to work on the postal server. Added an example snippet to support the SMTP authentication and correlated it with demo screenshot from the server itself.

Isn't this technically incorrect because the username is usually prefixed with the organisation slug? If you see above the list of credentials there is a link to the details to use for SMTP which shows the username (and first SMTP credential I think)

Hi @willpower232,

Thank you for your review—I really appreciate it.

My bad, I misunderstood earlier. I see your point now.

Isn't this technically incorrect because the username is usually prefixed with the organization slug?

So, you're saying this is correct? (See attached screenshot: correct_username_displayed_help.png)

It seems that the previous screenshot, smtp_credentials.png, was pointing to the friendly name (a.k.a. name) of the generated credential.

Replacing smtp_credentials.png with correct_username_displayed_help.png should fix the issue(within this PR), right?

What do you think? Thanks!

Yeah something like that 👌
