SparkPost Deprecating TLSv1.0 - next steps?

[Malcolm]

I'm a bit late on this scene and have been caught without preparing for this change. SparkPost's tip to maintain continuity doesn't help. Here's the advice,

"If you are using TLSv1.0, you should do one (1) of the following:

If you are using proprietary code, then have your in-house development team update the code to use at least TLSv1.1.
If you are using 3rd party software, then verify that your client supports at least TLSv1.1 and upgrade the client."
I am the 'development team' and I have no idea how to get my 'secret code' back into action.

Do the SparkPost users out there have any tips for my 'next steps?'

Thanks in advance.

Malcolm,

As there's no built-in SparkPost functions in V11 I've written my own. I'm now using this with AA as well as it's not possible to specify the security protocol using the built-in 'email_send_sparkpost()'.

Sample function below...

FUNCTION E_Send_SparkPost AS C (API_key as C, email_from as C, email_alias as C, email_to as C, email_subject as C, email_message as C, email_attachments as C, email_html_message as C)

dim result as C
dim send_it as C
dim ps as p
dim pm as p
 
result = email_smtp_open(ps, "smtp.sparkpostmail.com", 587, "SMTP_Injection",API_key, "STARTTLS")
if result then
	pm.from = email_from
	pm.from_alias = email_alias
	pm.to = email_to
	pm.subject = email_subject
	pm.message = email_message
	pm.attachments = email_attachments
	pm.html_message = email_html_message
	'Inline images for HTML messages - set IRelated to 'true' if sending inline images as attachments
	if email_html_message <> "" then
		pm.lRelated = .T.
	else
		pm.lRelated = .F.
	end if		
	send_it = email_smtp_send(pm,ps)
end if
result = ps.buffer
pp=email_smtp_close(ps)
E_Send_SparkPost = result
END FUNCTION

For desktop users, I've also been testing SparkPost using the Alpha email settings on the desktop and although you can't specifiy STARTTLS on the sending tab of the email settings form you can modify the windows registry directly with the correct value. For A5V11 the location is 'Computer\HKEY_CURRENT_USER\Software\Alpha Software\Alpha Five 11.0\init\email\profiles\profile1\SMTPSecureConnectionType' and should be set to 'STARTTLS' . A5V10 uses a similar path and AA uses 'Alpha Anywhere 12.0' Once set up this will work using the standard A5 emailing functions.

If you're supplying your own parameters then just specify "STARTTLS" in your email_smtp_open command instead of "TLS"

Hope this helps any others using sparkpost.
