--- Comment #23 from Jeremy Harris <[email protected]> --- Looks like you have a networking problem - nothing after the 192'nd byte of the TCP connection is being ack'd at the TCP level. We see the SMTP data go-ahead, and the next packet being sent by the kernel (the first one of the SMTP data) is 2774 bytes. That could get fragmented down to the interface MTU by the NIC, if you have offload enabled (likely) - we're not seeing the actual wire-size packets here. In any case, the far end isn't ack'ing. Summary: probable MTU issue on the net, compounded by ICMP being disabled. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
