Looking through, I agree this looks like a very awesome app, however I do have a slight problem in that I tried to install the server version of Ubuntu 7.04 and while it installed it crashed on initial startup. So, going to try my FC7 disk next to see if that fixes the problem. On 10/5/07, Jorge D

I had the same problem with Gentoo but then again i wasn't using a Gentoo kernel source, i was using Vanilla with User-mode Linux (SKAS) patches. I noticed the kernel modules are pretty picky, hopefully that'll change with time. It works nice with the RHEL5 kernel in CentOS 5. (2.6.18-8.1.4.el5) O

Please check out qmailtoaster. It even comes in an ISO that has the whole server side well integrated. It provides MTA, MDA, anti-spam, anti-virus, imap, pop, webmail, muti-domain support, certificates, and a web-based point & click interface so you don't have to learn too much. I've set up a

There is a note either on the site, or in the documentation that you should use 2.6.20 or higher due a race condition at boot time with 2.6.18/.19. Which might be the problem I am running into. I haven't spent a lot of time on it. Just remarking that initial run through was disappointing. Although

I agree with everything Darrin wrote, but would add a few things: On Debian, its all very easy. Make sure you have your apt sources set to download from the security tree, and update it somewhat frequently. Use Postfix/Dovecot - not only are they easy to setup, but they have a good reputati

Qmailtoaster looks great. Too bad it is an rpm and not Debian compatible. I didn't find any discussion if alien worked in this particular situation or not. I did find this write-up http://www.shupp.org/toaster/?page=preface#whatisatoaster which covered installing most of the bits of qmail toaster

By "in house" I meant into my server room at the office vs. the having it "professionally" hosted, so I have some $$ for bandwidth. As far as bandwidth, it will only work if we can get the COX feed we are looking for. (Engineers say by January, but I have heard it before) Rite now I have few T1's
