If it is a case of when you click send and receive on a mail client, it takes a long time before it checks it is probably the pop3 run file and not necessarily dns, although it may be dns related. The solution below solved slow pop3 login.
I had this problem in the past and it had to do with the pop3 run file, in my case at least. Although it was some time ago. Check /var/qmail/supervise/pop3/run It possibly looks like this exec /usr/bin/softlimit -m 9000000 \ /usr/bin/tcpserver -v -R -c 200 0 110 \ /var/qmail/bin/qmail-popup $HOSTNAME \ $PASSPROG /var/qmail/bin/qmail-pop3d Maildir 2>&1 I changed the tcpserver line to /usr/bin/tcpserver -l0 -H -v -R -c 200 0 110 \ (I added the -l0 and -H) It had something to do with stopping local or remote host dns lookup, I can't remember the specifics, but it changed from 60 seconds plus for pop3 login to virtually straight away. Try that. -----Original Message----- From: Ole J [mailto:[EMAIL PROTECTED] Sent: 26 April 2007 09:11 To: [email protected] Subject: Re: [qmailtoaster] Slow connecting pop3 server I might have done the djbdns wrong.
