The log messages shown above don't seem to indicate the actual connection, just the point where it finally gave up. You might need to add some debug logging in the connect, mail, and rcpt acl's (won't have a mail queue id, so make sure to log the sender ip address, $sender_address IIRC) so that you can identify the timing of this inbound email. If it was me, I would also start a tcpdump on the server, writing output to a file in pcap format, for a known IP exhibiting the symptoms, and then wait for an email delivery to be attempted, then examine the data in detail. Make sure to use -s0 to not limit the size of the packet it writes to the file. Are you sure that you are not blocking all ICMP? If you have all ICMP blocked at any hop between and including your border and your server, you break Path MTU Discovery (pMTUd) and then any feedback for sub 1500 byte paths are lost. Your description doesn't sound like it, but check it any way. ...Todd -- The total budget at all receivers for solving senders' problems is $0.
