We have a 2-member C300 cluster than currently processes incoming e-mail for about 30,000 people.
While I welcome the arrival of the oldmessage/showmessage/ removemessage commands in release 5.0, I'm still waiting for the Sendmail/Postfix 'mailq' equivalent, able to summarize the queue contents (MID, sender, recipient(s), size, arrival date) before feeling comfortable promoting the IronPorts as 'outgoing mail relays' or smarthosts.
Is there any chance of a similar command being added in a future release ?
"mailq" is a sendmail command that prints out the entire contents of the mail queue. The qmail equivalent (if you're familiar with qmail) is "qmail-qread".
As far as I have been able to tell, there is no documented AsyncOS command for doing this. A little bird once whispered in my ear that there might be a hidden command to accomplish this, but hidden commands aren't very helpful to the rest of us. Another little bird more recently whispered in my ear that this functionality might be made public in an upcoming release of AsyncOS.
But really, I wouldn't worry about it. You may not be able to examine every single message in the queue, but you can use existing commands like "tophosts" to spot particular domains which are being troublesome. That has so far always proven to be good enough for us.
Although it might not address all situations you could combine what dlnash stated and use 'tophost' or Outgoing Mail Delivery (in the WebUI) to find problem destination domains and restrict the command to the domain or sender e-mail address in question.
But you are correct it is limited to 1000 entries.
