Cannot send to domain

We have an IronportC160 that cannot send to lasllc.net. When anyone (three different senders). Sends an email to this domai, the log shows lookup an virus scans good, the message is queued for delivery. Three days later the log shows a delivery attempt that is rejected as being too old. Why is it sitting 3days? No other destination has the problem.

Hello,

please use the hoststatus command on the CLI to check what the problem could be:

CLI: hoststatus lasllc.net

Check if the host shows up or down, and if there are any errors at the end of the output. Also hoststatus gives you the destination IP(s) the IronPort tries to connect to, if they are not reachable for some reason, the appliance will keep attempting to send messages to that domain until delivery expires, in your case 3 days. This is set by your bounceconfig.

Hope that helps,

Andreas

PS: A uselful command to check connectivity is

CLI: diagnostic->network->smtpping

Use that to check the IPs given by the hoststatus command.
