I have installed several IronPorts at customer sites and when checking the units, i always see "message aborted" in mail_logs.
Sometimes it's might be bad senders and it's normal that the conenction is dropped.
But many times it just seemed that the connection is dropped for no reason.
Some customers have PIX, ISA,etc but i really don't understand why there are so much aborted messages.
For one customer, they were using a BorderWare MXtreme and when they shifted to IronPort, they started having messages aborted and even problems receiving large attachments.
Did anyone noticed that and do you have any idea whether it's a problem on the IronPort on network, MTU,etc?
