I was testing this again this morning, as it was some time ago that I did this, and it seems it's not just the -H it's a combination of the -l0 and -H.
They do the following I believe. (based on tcpserver paramaters.) -H: Do not look up the remote host name in DNS; remove the environment variable $TCPREMOTEHOST. To avoid loops, you must use this option for servers on TCP port 53. l localname: Do not look up the local host name in DNS; use localname for the environment variable $TCPLOCALHOST. A common choice for localname is 0. To avoid loops, you must use this option for servers on TCP port 53. Taken from http://cr.yp.to/ucspi-tcp/tcpserver.html For us that sorted the problem straight away, but I guess if rdns is the problem and you use/need it as eric said this would be a short term fix. -----Original Message----- From: Eric "Shubes" [mailto:[EMAIL PROTECTED] Sent: 07 November 2006 00:57 To: qmailtoaster-list@qmailtoaster.com Subject: Re: [qmailtoaster] slow pop3 logins That's certainly worth a shot, but I'd consider that a remedy instead of a fix. If adding the -H flag improves things, I would think then that reverse DNS is certainly the problem. I don't know enough about configuring (bind or djbdns) off hand to tell you how to fix it. Perhaps someone else here does. Do some digging, and I'm sure you can find a solution. Google is your friend. ;) slamp slamp wrote: > did you try Craig Smith's solution for the same issue he was having? > > From: "Craig Smith" <[EMAIL PROTECTED]> > To: <qmailtoaster-list@qmailtoaster.com> > Reply-To: qmailtoaster-list@qmailtoaster.com > Subject: RE: [qmailtoaster] Slow pop3 login > Date: Mon, 6 Nov 2006 11:30:13 -0000 > X-Mailer: Microsoft Office Outlook 11 > > Is this problem still occuring?
