problems with pop3 daemons
Im running a mailserver on FreeBSD 5.4, for some time now im experiencing problems with downloading large messages (above 1 mb but i don't know from which size it starts) through pop3: After about 30 secs of downloading, the download just hangs, qpopper's output to the logs is: ay 11 16:31:00 loki qpopper[57578]: I/O error flushing output to client xxx Operation not permitted (1). I tried to switch pop3 daemon, and tried popd, pop3lite and pop3ad.. all did the same thing but didn't report anything.. im using ipfw to limit the bandwidth to port 110 with the following rules: pipe 1 config bw 16KByte/s add pipe 1 tcp from me 110 to any although I tried turning ipfw off and got the same results. Im also using pf as my firewall and allowing ICMP with the following rules: pass in on $ext_if inet proto icmp from any to any keep state pass out on $ext_if inet proto icmp all keep state what can be the problem ?! ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

This is one for the qpopper mailing list, but to save you some trouble, the not pemitted is what qpopper reports when the client end of the connection has gone away and it finds it's writing to a closed socket. It gets seen on all kinds of platforms and is not a BSD issue, nor (usually) an OS configuration issue. This almost always indicates a buggy POP client which is failing on some message, and/or a client which is running AV software which transparently hijacks POP connections in order to scan them. In either case you need to see what's going on on the client end. qpopper is merely more verbose about reporting this than most POP servers. -- Clifton -- Clifton Royston -- [EMAIL PROTECTED] Tiki Technologies Lead Programmer/Software Architect I'm gonna tell my son to grow up pretty as the grass is green And whip-smart as the English Channel's wide... -- 'Whip-Smart', Liz Phair ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
