I am having trouble with a custom function in Zoho Flow, using invokeurl, with send_mail.
Error: "message": "Connectivity issue occurred when sending mail via your SMTP server",
I can get it to send just fine from one email, but not another. In other words. There are only problems with one email "from" address.
sendit = invokeurl
parameters: param + ""
* The connection is good.
* It does not seem to matter who I log in as.
* I created a new connection under the login email that is having trouble. But, that did not fix it.
* I gave the problem login email admin access to Zoho Flow, Zoho CRM, Zoho Creator.
Also, I can send just fine with the problem email using Notification > Send Mail. But, that method does not link it to the contact.
We use Gmail, and Zoho Flow is configured under Security > API Controls > Manage Third Party Apps Access. Are there settings in Gmail I can check, for the problem email?
