Aha.

These are probably the *OTHER* end of the listserv-sendmail connection
going away after the 'resource temporarily unavailable' error.  The fact
that the number of hits *increased* when you tweaked SMTP_FORWARD_1 indicates
that whatever is happening is doing so at a fairly low level.

I admit being at a loss for what resource could run out after the RCPT TO:,
but I'm feeling pretty confident that the problem is that the LSV side starts
sending the mail, gets into the RCPT TO phase, runs out of "something",
and closes the connection.  Lather, rinse, repeat.

Could you take one of those queue id's ( g8QFrghQ031672 for example) and
grep for *all* occurences in your sendmail log?  I'm curious about how many
recipients were listed, and exactly how far (and how fast) it got to the
point it died...
