I think DNS is working to a point, let me clarify a bit. I have both tinydns and dnscache running on the firewall machine and nowhere else. I am not using this domain on the lan and dmz. The lan is defined as kroffts.home and is on 192.168.1 The dmz is kroffts.com and is on 192.168.10 with http and mail DNATed from the internet or at least that is my intent :-) As I see it now I have two problems (at least) One is the excessive amount of time needed for qmail to respond to a pop3 request from the lan. I tested with a different mail client and found that it is in fact functional in both pop3 and smtp operations. It it just very slow. I did not time it but it takes 1 to 2 minutes for mail to be retrieved or sent. The time appears to be spent in authentication. The actual mail transfer is normal. The second issue is one of qmail not recognizing my users. I have created user accounts with entries in /etc/passwd and /etc/shadow and made a group entry in /etc/group. I used makemaildir to create mail directories for each user. I can log into these accounts locally or through ssh. I can use the logins to access pop3 through telnet. But when I send mail to these users, I get a returned message from qmail saying: Sorry, no mailbox here by that name. (#5.1.1) Aside from the group number the only difference I can see is that the lrpqmail user has a home directory entry where I have set the others to use /server/home as /server is the mount point for the ide disk that will store the mail. Since the login scripts seem to work and send the users to the proper home directory on logging in, I think qmail should recognize the Maildir's as well. I wanted to mount the /server/home as /home to reduce confusion. It seemed to me that I had used a command similar to mount /server/home /home before but it is not a valid command since mount seems to need a device identifier. I have read the man pages and still thing this relocation is possible but I need more research.
