I'd like to be able to send messages to the on-board spam quarantine via a message or content filter, but this doesn't seem to be allowed. I can send messages to other quarantines like Policy, just not to the spam quarantine. What I'd like to do is h...
I just downloaded the release notes for AsyncOS ESA 7.0.0 FCS. The very first thing I noticed was that it's now done in Cisco's documentation style. The assimilation continues. I liked IronPort's old style better.Just had to grump a little...

The destination of an SMTP route has an MX lookup performed on it. Make your default route point to a name that has multiple MX records of different weights.ALL: default.smtp.route $ dig default.smtp.route mxdefault.smtp.route. IN MX 10 primary.smtp....
Andrew,Whitelisting a particular email address happens at a totally different layer of the system, since email addresses aren't sent until after the SMTP connection is up. You'll want to set up an Incoming Mail Policy for that.++Don
We're seeing the same problem. Our outbound mail goes through a private listener with SBRS turned off. We scan for outbound spam to detect cracked accounts, and route spam positive messages to a quarantine. We've seen lots of false positives today. M...
