Claus,
Richard appears to have found a problem while sending a 45MB file to me
with 8.11.10. I guess it's time for you to join the thread. Please
review attached.

All done. It's already setup this way.
Ok. So please now show a tcpdump trace during the
sendmail -qso we can see what's going wrong in the TCP connection to the smtp server:tcpdump port smtp

I tried to send Jeff a 45 Megabyte file. It is still in the queue.

It isn't a TCP/IP stack problem. It may be a memory problem. Every time sendmail spawns a child to send the file data, it crashes. That's why the file never gets sent!
This is how /proc/meminfo looks right after it crashes. There has been a lot of swapping going on.
