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...
Does anyone know of a good list of domains which are known to sign all outbound mail with DK or DKIM? I'd like to start doing what Google has started doing as documented here:http://gmailblog.blogspot.com/2008/07/fighting-phishing-with-ebay-and-paypa...
Are there any plans for IronPort to implement Sender Rewriting Scheme in AsyncOS? I'm personally not a big fan of SPF and SRS, but like it or not they're being deployed. We use a C300 to operate a mail forwarding service for our alumni (we get the fo...

It means the incoming connection terminated before the SMTP client sent the QUIT command. It could mean that the client is badly behaved (the standard requires that clients always issue a QUIT command before closing the connection), or that the conne...
"No message injected within timeout period" means the SMTP client is connecting but not sending a message. Try turning on injection debugging to get an SMTP trace of the connection.++Don
Looks like the connection is getting dropped after the client says "DATA" and the IronPort says "go ahead". I wouldn't expect the IronPort to drop the connection immediately after saying "go ahead" (and besides, why would it do so only for this clien...
