Hi,
I have an issue when using custom sender in the email sending nodes. I have a very simple process with two email sending nodes in parallel. Both nodes are configured exactly the same, except for the sender type: one of them is 'Custom sender' and the other is 'Process'. I have tried different combinations in the 'Sender email' field, and nothing works.
To rule out that the email is going to a spam folder, I have put a personal email in the recipient email, and only the email configured with 'From: Process' arrives, just as it happens when I use a corporate email.
Furthermore, in the 'Sender email' field, I have tried using both the toemailrecipient() function and the toemailaddress() function.
Neither of the nodes gives an error. Any ideas on what might be happening?

The issue is, that the Appian mail server tries to send an email for a sender domain it does not own. To make that work, you will have to reach out to your mail server admin.
I'd worry that the incoming email from the custom sender is being filtered by your corporate mail server (i've seen this issue before, since the alleged sender's domain doesn't match the SMTP server's domain, or something along those lines).
To test, change that node to send to your personal gmail address and retry.
If this is the issue you'll need to chat with your SMTP admin as Stefan has already mentioned.
