SMTP smarthosts: authenticated and non-authenticated

[unco]

Hi!

Here's my situation. I have domain users who send out through mailgun and duocircle, and they need to be authenticated. That works fine. Everyone else is sent out through SpamExperts. That works. I also have several domains whose email should go out through Barracuda's message service so they can be encrypted. That has stopped working. I don't know when that stopped, but I suspect it was when I set up the authenticated senders for mailgun and duocircle.

Does anyone have a working exim.conf.local containing this scenario?

If I need to explain better, please let me know!

Thanks,
Beth

Here is the error message I am getting when a message delivery is attempted to one of the unauthenticated smarthosts (Barracuda).

R=smarthost_regular defer (-30): transport "remote_smtp_smart_regular" not found in smarthost_regular router

I found the problem, and everything's working. Here's my exim.conf.local
