Hi, The situation: 2 machines, pigeon.pigeonloft (192.168.1.1) and nestie.pigeonloft (192.168.1.2). pigeon is the main machine, nestie is the gateway, connecting via dialup.
nestie receives incoming email with fetchmail and hands it over to exim, which forwards it to pigeon. This works fine with small numbers of emails, ie. my normal combination of a few personal emails and mailing lists in digest form. Recently I subscribed to the linux-kernel list in order to see what is being said/done about 48-bit IDE support. This brings in wads of messages as the linux-kernel list doesn't have a digest (afaik). The first 40 or so emails are received and forwarded OK, but after this /var/log/exim/mainlog suddenly gives me: 2003-02-15 16:08:25 18k4rZ-00005T-00 <= [EMAIL PROTECTED] H=localhost [127.0.0.1] U=pigeon P=esmtp S=3392 [EMAIL PROTECTED] 2003-02-15 16:08:25 18k4rX-00005T-01 => [EMAIL PROTECTED] R=lookuphost T=remote_smtp H=pigeon.pigeonloft [192.168.1.1] 2003-02-15 16:08:25 18k4rX-00005T-01 Completed 2003-02-15 16:08:27 18k4ra-00005T-00 <= [EMAIL PROTECTED] H=localhost [127.0.0.1] U=pigeon P=esmtp S=16886 [EMAIL PROTECTED] 2003-02-15 16:08:27 18k4rZ-00005T-00 => [EMAIL PROTECTED] R=lookuphost T=remote_smtp H=pigeon.pigeonloft [192.168.1.1] 2003-02-15 16:08:27 18k4rZ-00005T-00 Completed # WTF are these next 2 lines all about??? 2003-02-15 16:08:28 18k4ra-00005T-00 Remote host pigeon.pigeonloft [192.168.1.1] closed connection after initial connection 2003-02-15 16:08:28 18k4ra-00005T-00 == [EMAIL PROTECTED] T=remote_smtp defer (-19): Remote host pigeon.pigeonloft [192.168.1.1] closed connection after initial connection 2003-02-15 16:08:30 18k4rc-00005T-00 <= [EMAIL PROTECTED] H=localhost [127.0.0.1] U=pigeon P=esmtp S=18807 [EMAIL PROTECTED] At this point the dialup is still connected and nestie is still downloading mails, but they aren't being forwarded to pigeon. Log entries after this are full of "defer - retry time not reached". If, once the dialup connection is closed, I try exim -qf to push the messages on to pigeon, nothing happens apart from the log filling up with "connection refused". If I now reboot nestie and try exim -qf again, all the mails are forwarded to pigeon quite happily, even though there are probably many more than 40 (the number at which I first had the problem). This suggests to me that the problem is not really pigeon refusing connection, but nestie ceasing to be able to make the connection. Running nestie's /etc/init.d/networking restart makes no difference. On both machines exim.conf has smtp_accept_queue_per_connection set to 100. Does this look familiar to anyone? Where should I be looking for the fault? Pigeon -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
