Sendgrid API Key Mail Server Settings

Anyone else using Sendgrid with Coldfusion 2023? We are using the Sendgrid SMTP API, https://www.twilio.com/docs/sendgrid/for-developers/sending-email/integrating-with-the-smtp-api, and the issue is with the password. They have you create an API key for the password, and the key is 70 characters long in the format SG.xxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. When entering this as the password in the Coldfusion administrator mail server settings, and doing a test with cfmail, mail.log shows the error "Can not decode string "SG". The input string is not base64-encoded." All we can think is Coldfusion is treating it as a JWT since it has two dots in the string. When entering anything else, we get the normal authentication error in mail.log. Also tried the cfadmin API to set the mail settings and have the same issue. Can you think of a way we could change the way we enter the password in the mail settings? We could always use the Sendgrid Web API instead of SMTP, but would really hate to update all of our cfmail tags. Any ideas would be appreciated!

I am getting the same error with SendGrid and CF2025. Did you resolve this by any chance?

Any update on this, Adobe? (To save people time, Adobe had marked the bug report by @TwoEdge as a duplicate of the one shared by @fishburp above, https://tracker.adobe.com/#/view/CF-4226870.)

Sadly, while Adobe has marked the original bug report as "to fix", there's no indication there of "when" it will be fixed, or if indeed there is currently any hotfix (awaiting release in a full update). To be clear, I've confirmed it's not working even on update 4, the current lastest CF2025 update.

Can either of you two above, or anyone else (or Adobe), clarify whether perhaps such a hotfix jar has been made available to you directly?

It's indeed pretty sad that folks using CF2025 can't send via sendgrid, still 8 months after CF2025 came out and 4 months after the bug report was filed.

Well, this was a known issue prior to it being fixed in cf2023 (and 2021) in the Oct 2023 cf update. That's update 5 for cf2023. What update are you on?

Here's the indication of it being fixed back then:

Thank you for the reply Charlie and apologies, I mistakenly typed 2023, but it is actually Coldfusion 2025.. I did see that fix for 2023, so I was suprised when we saw an issue on 2025.

That's certainly interesting to hear. Either something changed again about the format of the key/password, or somehow Adobe forgot to include this fix in 2025 (which seems unlikely).

Either way, you may or may not get any reply from them here. Your best bet is to report it to them either via cfsup@adobe.com or by opening a ticket at tracker.adobe.com. The latter will benefit more people, as it would be viewable by all.

In fact, someone had reported it back in 2023, before it was fixed for those versions. Indeed, before writing my first reply here I'd seen that someone had commented there that it was happening for them on 2025. You'll see I'd suggested to them also to open a new ticket, since that one was marked fixed back in 2023.

If you do file a new ticket, please do share the link here and there, so that interested folks can add a vote or comment and follow along in any news there from Adobe.
