(This is my second attempt to send this to the mailing list. I am, as
the message I got the first time, behind an exploder. I've now
subscribed from my main account and I suppose I'll just have to
procmail out the mailing list traffic.)
Please observe the bounce message below. You'll see that Exim (1.82,
config file included below the bounce) has been unable to deliver this
message correctly due to failure to agree on how to do SMTP correctly
when talking to another instance of Exim 1.82 !
This effect happens much more when I say `-odqs' when injecting these
mailing list messages; presumably this encourages Exim to reuse
connections which are in strange states.
I haven't straced or tcpdumped a failure of this nature, not having a
scratch machine to play with. In the meantime I've removed the -odqs
and am doing immediate delivery, which appears to greatly reduce or
eliminate this problem (perhaps I then get hardly any connection
reuse).
The Exim source I'm using is Debian's 1.82-7; the diff between that
and stock 1.82 doesn't touch the core Exim source at all. I compiled
the binary myself from that source code.
Ian.
