It's been a little while since I last tried to send an email, so I'm not sure how long it's been like this, but when I attempt to send anything today, I get the following error:
SMTP Error: [451] 4.3.5 <DATA>: Data command rejected: Server configuration problem
And of course the email is not sent.
I have not noticed any issues receiving mail.
My apologies, but the rate-policy daemon stopped running for some reason. I was out of town all weekend for a convention, or I would've gotten to this sooner. I've corrected the problem, and it's up again, so email should work as expected. Please let me know if you have any more problems.
Thanks so much! Everything appears to be back to normal now.
