Ahoi there

My website sends emails via the Zoho's SMTP from my email account and when they're undelivered I see them flagged with a red exclamation mark in the "Sent" box.

This has caused me today some bounces that disabled my account for a few minutes.

I want to track these messages with the api and temporarly block from sending emails to them and show a warning to the user - is that possible via the api to get a list of undelivered emails?

Thanks a lot

Avni.
