It's trying to send copies to hotmail


New Email
This seems to pop up only when I send an email from my gmail account to one particular person, who has a Juno email address. The email gets through but I get a response saying
11:48 PM (6 minutes ago)

to me

Unfortunately, your mail was not delivered to the following address:


Connected to xxx.xx.xx.xx but sender was rejected.
Remote host said: 550 5.7.1 Unfortunately, messages from [] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3150). You can also refer your provider to Troubleshooting. []

It's not the end of the world since the emails get through, but it's annoying. Any ideas?

Thank you!

Hi @goanaddo,

It appears your Juno contact may have automatic email forwarding enabled. If the issue is only with that contact, I'd send a note letting them know to check the email forwarding & filters settings on their end.
