I don't understand why I have started getting this problem. Here is my setup: Potato installation with 2.4.4 kernel using Adrian Bunk's .debs Connect to ISP using standard dialup modem - using pon Download mail with fetchmail Fetchmail delivers it to postfix Postfix gives it on to procmail Then I finally read mail with mutt This setup has been working fine for the last 6 months or more. And I have the same setup with exactly the same config files for postfix and fetchmail on another computer running the same kernel version and it still works fine. Last week, I started getting these errors in my syslog when trying to download my mail: Nov 16 12:07:44 flea fetchmail[455]: starting fetchmail 5.3.3 daemon Nov 16 12:07:58 flea fetchmail[455]: 262 messages for mdevin at pop.ozemail.com.au (812090 octets). Nov 16 12:07:59 flea fetchmail[455]: reading message 1 of 262 (3327 octets) Nov 16 12:08:00 flea fetchmail[455]: SMTP connect to localhost failed Nov 16 12:08:00 flea fetchmail[455]: SMTP transaction error while fetching from pop.ozemail.com.au Nov 16 12:08:00 flea fetchmail[455]: Query status=10 (SMTP) I have not changed anything recently, which make this all the more weird. So, just to make sure that everything was the same as on my other computer that works still, I copied the /etc/postfix/main.cf file from it over and only changed the hostname as required in the file. But on trying again, it still gives these errors. I have also tried telnetting into port 25 and, although I am not quite sure how to do this, it does seem to work OK: algemon@flea:~$ telnet 127.0.0.1 25 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 220 flea.home.net ESMTP Postfix MAIL FROM: <mdevin@ozemail.com.au> 250 Ok I wasn't sure what to do next so I just did ^c and aborted from it. However, it did seem to let me connect. Does anyone have any ideas on how to troubleshoot this further? It may be a hardware problem, because I have hardly used this computer recently and certainly haven't changed any software config files or the like recently. Thanks for any help. Mark.
