AFAIK a broken pipe occurs if you try to write on a socket that isn't
connected anymore. So for instance, the initial connection to spamd
succeeded, but then spamd died / restarted or the connection got
terminated otherwise, and when you tried to write to the socket it
failed because there was nothing to write to.

There *WAS*. sa-exim PANIC'ed, and because of that, sa-exim didn't know
what to do with the message and told exim to temp-reject it.

sa-exim runs after the DATA section has been closed.

I do.
I'm 99.9% sure it had to do with spamd / spamc not functioning correctly.

You see the line that caused the error is in fact a write() to a
filedescriptor. If you look up on where that filedescriptor is defined
you'll most certainly find it's a connection to spamd.

Take care,
Sander.
