Exactly the same issue for me. I’ve also tried WP Mail SMTP plugin and I receive the same error

Have you been able to get any support for the issue? I haven’t unfortunately.
Try clicking to not allow other plugins to send from a different address, see if that helps?
Whatever is generating your email in WordPress is sending the text {site_url} to Postman for the From email address. Obviously that is incorrect and Postman is rejecting it before your mail server does.
You must fix whatever is generating that email. Alternately, you can tell Postman to ignore the From fields sent by other WordPress plugins in the advanced settings and only use what you’ve entered.

Thank you Jason. This is what I did, and it seems to be working correctly now.
Thanks Jason, yeah completely right. Was coming from white label branding plugin.
Working now. Many thanks!
Glad you got your issue sorted out too abaloo 🙂

@shanelives that’s interesting, I was using White Label Branding on my site too. Wonder if there is a conflict there?
@abaloo if you go into the WLB settings and go to Branding -> Email Branding
In there, I found the {site_url} shortcode in the From field which was causing the issue as Jason pointed out. Its probably the same for you
