Hi All, Well, I'm really stuck and need help. I'm grasping at straws to figure out what caused the problem I am having. Here is the problem (I have posted this in other threads. I'm still trying to find a solution) Running FC3, KDE 3.3.1-2 and kmail 1.7.1. I'm using qmail (from qmailrocks.org) to recieve mail for all users on my network. Everything has been working great up to a couple of days ago. Then, mail stopped coming in or going out. In checking the logs, I found that yum had installed exim and that messed everything up. So I stopped exim and now mail is coming in and going out as normal. I read my mail on the same computer that the mail server runs on. When I start kmail, it posts an error dialog: "Cannot start process pop3" and then does not bring in my mail. I used netstat to verify that tcpserver (from qmailrocks) is listening on port 110. I can "telnet localhost 110", log in and list my mail, so I know that the pop server is alive and working (plus other users can get their mail). I ruled out my firewall (turned it off, briefly and got the same error message. I also ruled out hosts.deny and hosts.allow, since they are empty. I'm guessing that something that yum installed/updated on my system has caused my problem, but I don't know. Its only a guess. Here is what yum installed when the problem began (when this problem occurred, I turned the automatic updating by yum off. I do learn from my errors) Jul 22 04:39:30 Installed: exim.i386 4.43-1.FC3.1 Jul 22 04:39:32 Updated: mozilla-nss.i386 37:1.7.10-1.3.1 Jul 22 04:39:50 Updated: thunderbird.i386 1.0.6-1.1.fc3 Jul 22 04:39:51 Updated: fetchmail.i386 6.2.5-7.fc3.1 Jul 22 04:40:02 Updated: firefox.i386 1.0.6-1.1.fc3 Jul 23 04:46:40 Updated: perl.i386 3:5.8.5-14.FC3 Jul 23 04:47:15 Updated: kdenetwork.i386 7:3.3.1-3.2 Jul 23 04:47:15 Updated: kdenetwork-devel.i386 7:3.3.1-3.2 Jul 23 04:47:17 Updated: mgetty.i386 1.1.31-3_FC3 Jul 23 04:47:18 Updated: perl-suidperl.i386 3:5.8.5-14.FC3 Will someone PLEASE help me figure out what has caused this error and what to do to correct it? I'm at a loss. Many, many thanks, Mark
