Hello, everyone.
This morning, I have discovered a very strange e-mail issue that I could use some help with. As a bit of background: I currently run two e-mail accounts through Outlook 2016. They are my University e-mail account, and my personal g-mail account. When I send an e-mail to a particular e-mail address in my g-mail account through Outlook, I get the following error message: Delivery to the following recipient failed permanently: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain by d105412a.ess.barracudanetworks.com. [64.235.150.252]. The error that the other server returned was: 550 Service unavailable; Client host [mail-io0-f173.google.com] blocked by zen.spamhaus.org; 24.231.151.149 (Note: I have deleted the e-mail address from the message in order to protect the person's privacy.) I have no problems at all sending an e-mail to this exact same address using my University e-mail account and outlook. This would lead me to believe that something is wrong with my g-mail account, but I can't figure out what, or how to fix it, especially since I know the e-mail address I'm using is accurate. Any suggestions would be appreciated. Dr. Tom Behler from Michigan For answers to frequently asked questions about this list visit: http://www.jaws-users.com/help/
