I'm certainly no expert, but your hosts file doesn't look right to me. Here is what I have in my /etc/hosts file:
127.0.0.1 mail.fqdn.tld localhost.localdomain localhost 192.168.1.2 mail.fqdn.tld localhost.localdomain localhost Obviously the second line starts with the ip address of my mail server, which you would change for your mail server, and the full domain name in mail.fqdn.com, which also needs changed. I don't think 0.0.0.0 is correct. jason -----Original Message----- From: Warner Moore [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 26, 2006 9:26 AM To: qmailtoaster-list@qmailtoaster.com Subject: Re: [qmailtoaster] IMAP Issues On Tue, Apr 25, 2006 at 03:38:34PM -0500, Erik Espinoza([EMAIL PROTECTED]) wrote: > I have about the same number of users on one of the QmailToaster > servers.

Usage is low, always. Currently, we're near peak staffing: total used free shared buffers cached Mem: 1034560 305212 729348 0 87436 42780 -/+ buffers/cache: 174996 859564 Swap: 2096472 68264 2028208 > 5) Does your hosts table have just localhost and the fqdn defined? That and an additional definition for a local server. Everything looks to be in order there: 127.0.0.1 localhost.localdomain localhost 0.0.0.0 mailserver mailserver.2checkout.com > 6) What kind of delay do you see when you telnet, does it take a while > for the IMAP banners to pop up? Yes, that is specifically what I was referring to before. > 7) Have you migrated from an older version of QmailToaster (such as > the old 1.0 branch w/ horde) No-- there have not been any major changes yet. > 8) Are most of your users accessing the QmailToaster's IMAP through > some sort of firewall? > IE > > Users -> PIX DMZ -> QmailToaster Yes, they're routing through our iptables implementation for the office network. > 9) Does it make a difference if you disable the iptables firewall > (temporarily for testing of course) That would be difficult to do, as they are on different areas of the network.

It's pointing to the static. > Sorry for the large number of questions. No problem, I appreciate the interest. > If you have some time, maybe we can speak on IRC later. Certainly.. network/channel?
