Message status not showing sent IP when sending using API (but does when sending using SMTP) about postal HOT 3 CLOSED

The source address is only present in the log when using the IP pools functionality. If you aren't using this, the mail will be sent from the IP address on the server itself and is outside of the Postal's control.

If you'd like to appear, you can enable IP pools 😄

I actually do have IP pools enabled.

The IP seems to conditionally appear based on how I give the message to Postal. If I send the message through the UI, the IP does show up. If I send through my SMTP credential, the IP does show up. If I use the raw API endpoint, the IP does not show up.

Is there a reason it shouldn’t show up just because it was sent with the API?

Okay, I found my issue. If a sending domain doesn’t have a rule to map it to an IP pool, it won’t show an IP.
My SMTP sender was specifying a different address which did map to a rule.

Interestingly, I just changed the Postal mail server’s default IP pool, and then changed it back, and now the IP is showing for that address even though it doesn’t map to a rule. 🤷‍♂️

I’ve always noticed some “slightly” strange behavior with the default IP pool when the default IP pool is automatically chosen by Postal rather than being manually specified, but as soon as I specify the IP pool, all that slight weirdness goes away so it’s not really a problem.

Sorry for any confusion I may have caused and thank you for all the great work you do! It is really appreciated.
