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... -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
