Webhosting, sort of..


Well this will all sound simple enough but I want a few expertsí opinions on security issues, configuration, favorite programs, etc. What I have (or need) is a webhoster in a sense. The company has a LAN running win2000 all around and a Linux firewall/router I setup. Then on a static IP (outside the firewall) I want to put their www/ftp/mail server. We have multiple domain names that all point to this IP. One of the domains should take you to the main html page and the other two names to a sub page. This one I can probably figure out for myself. Next is the FTP. This is only running for publishing the web pages so I only allow one user access. I have experience with apache(2) and VSFTP and got those installed no problem. Now the part I have no idea on, mailers. I put postfix, ipop3d, pop2d and imapd thinking this would be enough. This may be too much, I don't know.
What I want is a secure mail server that relays based on a username/passwd auth with pop3s for checking mail if possible. I cannot restrict relays on a network basis because some users are roaming and not always on the same address. I'm also not crazy about imap since I don't have much need for folders and I hear it's not so secure. I used and want to keep SuSE 9.0 for the OS since I like the fact I only install what I need and it has a nice package updater. I have setup sendmail before and it worked OK when I wanted to check mail but didn't like to relay it from outside sources. My fix to that was put squirrelmail on and everything that was sent was then locally generated and delivery was no problem. Now it's the opposite. I can send mail from an OL2002 client but can't check my mail. I also noticed the mailer is relaying everything, DO NOT want this happening. I made sure all the popds and imapd are turned on in xinet, but still can't retrieve mail. As for the multiple domains I mentioned earlier, I setup all the DNS info on the domain registration site, they let you manually edit the zone files, and set an MX record for all domains to my IP. It needs to accept mail for all of these domains, and only these domains. As for outgoing mail, I don't really care if everything appears to be coming from the main domain name (ex. user1@b.com and user1@c.com always shows user1@a.com) as they are a subdivision of the main company. Any tips as to changes to make to the default postfix main.cf that SuSE makes and/or other programs that do what I'm after would be greatly appreciated
