Progress....

I decided to wipe the slate clean and do a fresh install, since I was thinking the restore from v6 might have gone weird. In addition, I noticed that there were some fsck errors on bootup. As soon as I setup everything, many messages were being blocked for RBL violations (much more than before).

I had to create exceptions for the safe domains for them to get through at all. While watching the live SMTP log, I could see the message I was testing hit Astaro, but they wouldn't deliver to my mail server until the exception was entered. They were nowhere to be found in the Mail Manager either.

Is the spam filter really that restrictive out of the gate, with no configuration? If so, if rejected email from legitimate sources do not show up in the mail manager or in the notification reports, how am I supposed to monitor that? Watching the SMTP log obviously would be a bit tedious

Do you have any best practices for configuring the spam filter?

Thanks again for the help. We are definitely moving forward.
